@livid oak heres another error for context: Config invalid

Run: openclaw doctor --fix

The error means your agents.defaults.compaction.mode has an invalid value. The valid options are:

default - uses the built-in compaction summarizer
safeguard - uses chunked summarization for very long histories

Check your config at ~/.openclaw/openclaw.json and make sure compaction.mode is one of these two values (without quotes around it as a string value, it's a JSON5 field).

If you had something like "auto" or another value, change it to "default" or "safeguard" and run openclaw doctor --fix again.

Want me to help you check what's currently in your config?

Can you share what's in your config file around the compaction settings? Run:

cat ~/.openclaw/openclaw.json | grep -A5 "compaction"

Or paste the whole agents section if you're comfortable sharing it. The error means the current value is invalid (not default or safeguard), so we need to see what you've got there.

Found the issue! "balanced" isn't a valid compaction mode. Change it to either:

"default" - standard compaction
"safeguard" - chunked summarization for very long sessions

Edit the config:

nano ~/.openclaw/openclaw.json

Find "mode": "balanced" and change it to "mode": "default" (or "safeguard").

Save, then run openclaw doctor --fix again. That should fix it!

Based on this error, your agents.defaults.compaction.mode has an invalid value. Common valid values for compaction mode are:

Likely valid options:

"auto" - automatic compaction
"manual" - manual compaction only
"disabled" - no compaction

To fix this:

Check your current config:

cat ~/.openclaw/openclaw.json | jq '.agents.defaults.compaction'

Fix the mode - if it's a typo or invalid value, update it to one of the valid options above.
Run doctor again:

#

   openclaw doctor

Can you share the relevant section of your config? Paste:

cat ~/.openclaw/openclaw.json | jq '.agents.defaults.compaction'

That will help identify exactly what value is causing the validation error. The mode should be a string like "auto" or "manual", not an object or invalid value. 🦐

Now there's a JSON5 syntax error - the file format is corrupted. The : at position 1:9 suggests the file doesn't start properly (like it might have regular JSON or some other format mixed in).

To diagnose, please run:

head -20 ~/.openclaw/openclaw.json

Or share the first few lines - that will show what's at the beginning of the file that's causing the syntax error. The file should be valid JSON5 format (like JSON but with comments, unquoted keys, etc. allowed). 🦐

Found the issue! The config file is missing the opening { at the very start.

Your file starts with:

"meta": {

But it should start with:

{
  "meta": {

To fix:

#

# First backup the file
cp ~/.openclaw/openclaw.json ~/.openclaw/openclaw.json.backup

# Then edit it to add the opening brace at the start
nano ~/.openclaw/openclaw.json

Make sure line 1 is just { on its own, then the rest follows.

Or regenerate a fresh config:

openclaw configure --reset

This is a common mistake - the wizard or a previous edit accidentally removed the opening brace. Once you add { at the start, the JSON5 parser should be happy. 🦐

#

i fixed it but now its saying theres now space left on the vps

#

the disk of the vps

#

when i hit exit to leave editing, should i hit the append shortcut?

#

also save modified buffer?

livid oakBOT Jan 31, 2026, 2:14 PM

#

stark trail the disk of the vps

Ah, that makes sense! Full disk often causes file corruption - writes get cut off mid-file, which explains the missing { at the start.

Check disk space:

df -h

Common VPS disk cleanup:

# Check what's taking space
du -sh ~/.openclaw/logs/ 2>/dev/null
du -sh /var/log/ 2>/dev/null

# Clear old logs (if disk is full)

#

rm -rf ~/.openclaw/logs/*.log.old 2>/dev/null

# Or the nuclear option if desperate:
# rm ~/.openclaw/openclaw.json  # then re-run configure

If the disk is full (df -h shows 100% or close), you'll need to free up space before the gateway can start properly. 🦐

livid oakBOT Jan 31, 2026, 2:16 PM

#

stark trail also save modified buffer?

Yep, that's nano asking if you want to save your changes!

Quick nano reference:

| Key    | Action                           |
| ------ | -------------------------------- |
| `Y`      | Yes, save changes                |
| `N`      | No, discard changes              |
| `Ctrl+O` | Save (write out) without exiting |
| `Ctrl+X` | Exit nano                        |
| `Ctrl+G` | Help                             |

So hit Y to save, then it will ask for the filename - just hit Enter to confirm.

Then run:

#

openclaw doctor

Should be happy now! 🦐

stark trail Jan 31, 2026, 2:16 PM

#

theres a second step after editing

livid oakBOT Jan 31, 2026, 2:18 PM

#

stark trail

Perfect! The file looks correct now with the opening { in place. 🦞

Just press Enter to save with the current filename, then run:

openclaw doctor

Should be all good! 🦐

stark trail Jan 31, 2026, 2:19 PM

#

append or prepend?

livid oakBOT Jan 31, 2026, 2:20 PM

#

stark trail append or prepend?

That doesn't sound like standard nano behavior. What are you seeing?

Is it from:

A different editor or command?
A tee command or redirection?
Something else?

If you're still in nano, just hit Enter to save. If it's a different prompt, let me know what you're running! 🦐

#

now openclaw.json has been corrupted

#

is there anyway to restore it?

livid oakBOT Jan 31, 2026, 2:26 PM

#

stark trail is there anyway to restore it?

Yes! You have options:

1. Restore from your backup (if you made it):

cp ~/.openclaw/openclaw.json.backup ~/.openclaw/openclaw.json

2. Regenerate with the wizard:

openclaw configure

3. Copy from the default template:

cp /usr/local/lib/node_modules/openclaw/dist/config/template.json ~/.openclaw/openclaw.json

#

Or check where OpenClaw is installed:

which openclaw && ls -la $(dirname $(which openclaw))/../lib/node_modules/openclaw/dist/config/

Which backup option works for you? 🦐

#

Let me give you the simplest options:

Option 1: Re-run the configure wizard (easiest)

openclaw configure

Option 2: Manually create a minimal config:

cat > ~/.openclaw/openclaw.json << 'EOF'
{
  "meta": {
    "lastTouchedVersion": "2026.1.29",
    "lastTouchedAt": "2026-01-31T14:30:00.000Z"
  },
  "wizard": {

#

    "lastRunAt": "2026-01-31T14:30:00.000Z",
    "lastRunVersion": "2026.1.29",
    "lastRunCommand": "configure",
    "lastRunMode": "local"
  },
  "auth": {
    "profiles": {}
  },
  "agents": {
    "defaults": {
      "compaction": {
        "mode": "auto"
      }
    }
  },

#

  "gateway": {
    "bind": "loopback"
  }
}
EOF

Option 3: Delete and reconfigure

rm ~/.openclaw/openclaw.json
openclaw configure

Go with Option 1 - just re-run openclaw configure and it will walk you through setup again! 🦐

stark trail Jan 31, 2026, 3:09 PM

#

i got it back but then it locked itself up in some sort of loop after editing the config file

Perfect! That's exactly what you need to do - run through the configure wizard.

Just select "Local" (or "Cloud" if you're connecting to a remote server) and follow the prompts. The wizard will ask about:

Your model provider (Anthropic, OpenAI, etc.)
API keys or tokens
Channel setup (WhatsApp, Discord, etc.)

Go ahead and run through it! 🦞
