"invalid data" error when using deno cache | Deno | Page 1

I have a fresh project and I'm using the recommended Dockerfile. Ocasionally, when docker building, deno cache fails with this error:

error: invalid data
    at https://deno.land/x/fresh@1.2.0/src/server/render.ts:1:32

running it again usually works. I'm guessing it could be a weird network error, but I'm having trouble pinpointing where it's coming from, and the error message could be better, I think. I don't understand where it comes from. I tried running it with --log-level debug but it doesn't help much. Here are two excerpts, one where it fails and one where it succeeds:

The line in the stacktrace is an import: import { renderToString } from "preact-render-to-string";. I have the following import map: "preact-render-to-string": "https://esm.sh/*preact-render-to-string@6.1.0".

#

How can I figure out where the "invalid data" message is coming from? I don't see it in deno's repository nor in fresh's repository. Is it cause by import erroring out trying to download that preact render to string file, or something?

happening to me too. a simple create new fresh 1.2.0 app showing "invalid data". Quite frustrating as I was thinking of using fresh for starting my project.

I can reproduce it on one of my machines now too. Going to look into it but I can't fathom this being an issue with fresh itself. Will keep you posted once I have news

For some reason I can't reproduce that anymore :S

Hi all, just an update from my side, I managed to get this to work by removing * from deno.json on all urls from esm.

example: https://esm.sh/*preact-render-to-string@6.1.0 , remove the * becoming https://esm.sh/preact-render-to-string@6.1.0

#

But well now it can't run haha sigh

#

owh ok it works after deno cache --reload main.ts

#

the latest try was to change back one by one to add * and run
deno cache --reload && deno task start everytime and now it suddenly works fine now with default settings. wow. such a weird thing.
