#Soroban example Deployer contract fails on deploy

I am trying to implement the Soroban example Deployer contract and it fails.
Step 1: deploy basic test contract as shown in example code in the CLI, it works
Step 2: deploy custom contract with extra args in the CLI: it works
Step 3: deploy custom contract in Node using SDK and scVals: it breaks
So I guess it has to do with the native to scVal type conversion, as the CLI takes all strings and it does the conversion itself, and it works

#

Here is the error:

HostError: Error(WasmVm, InvalidAction)

Deployer signature:

        env: Env,
        deployer: Address,
        wasm_hash: BytesN<32>,
        salt: BytesN<32>,
        init_fn: Symbol,
        init_args: Vec<Val>,
    ) -> (Address, Val) {
#

Args passed as address, bytes, bytes, symbol, vector

#

Custom contract constructor:

#

Vector with args passed as [address, u128, address, address, i128, address]

#

Should it be a map instead of array?

#

Call in Node using SDK:

    const opr = ctr.call('deploy', ...args)
#

And it fails in the simulation with the error above

#

Finally, here are the args converted to scvals:

    const orgwallet = 'GDDMYQEROCEBL75ZHJYLSEQMRTVT6BSXQHPEBITCXXQ5GGW65ETQAU5C'
    const deployer = new Address(orgwallet).toScVal()
    const wasm_hash = nativeToScVal(Buffer.from('d44487d42355ac978ddb16c28ac4672d91771e918bab07e2cc4c768e7f6fcee6'), {type: 'bytes'})
    const salt = nativeToScVal(Buffer.from(randomNumber(10)), {type: 'bytes'})
    const init_fn = nativeToScVal('initialize', {type: 'symbol'})
    const owner = 'GDDMYQEROCEBL75ZHJYLSEQMRTVT6BSXQHPEBITCXXQ5GGW65ETQAU5C'
    const admin = new Address(owner).toScVal()
    const initiative = nativeToScVal(1, {type: 'u128'})
    const provider = new Address('GCFED2OC5W2S46UYVUY6K3CDFXTCIY2FHU3RN2FM4P2WT224OYTTJXUL').toScVal()
    const vendor = new Address('GAXSRTCK6PFIQHNULHBEJOI4VV2T7YS7SZCXBP6CGGYRI56LCWWMZO7I').toScVal()
    const bucket = nativeToScVal(20*10000000, { type: 'i128' })
    const xlm = new Address('CDLZFC3SYJYDZT7K67VZ75HPJVIEUVNIXF47ZG2FB2RMQQVU2HHGCYSC').toScVal()
    const init_args = nativeToScVal([admin, initiative, provider, vendor, bucket, xlm], {type: 'vector'})
    const args = [deployer, wasm_hash, salt, init_fn, init_args]
#

Values hardcoded for simplicity

#

Should I convert args to vector too?

#

What does VM call trapped: UnreachableCodeReached mean?

#

Is that in the deployer or the custom contract?

#

What does VM call trapped: UnreachableCodeReached
that means that your Wasm has panic'd for whatever reason (e.g. an explicit panic!, or a runtime error like division by zero). one frequent reason for that is passing arguments in bad format (the panic happens at the SDK level)

it seems your salt is not 32 bytes

hushed locust
#

hello?

last ledge
#

it seems your salt is not 32 bytes
Will fix that and try again

#

Ok, fixed the salt to 32 bytes but still doesn't work

#

Now the question is, why the wasm_hash is 64 bytes? Or am I converting it wrong?

# 
Bytes(3234393731323637333332363833313632313733363635363939303132393237),
#

According to the deployer signature it has to be 32 bytes too, same as the salt

# 
wasm_hash: BytesN<32>,
salt: BytesN<32>,
#

This is the wasm_hash d44487d42355ac978ddb16c28ac4672d91771e918bab07e2cc4c768e7f6fcee6 according to the CLI when installing the contract

#

And this the JS assignment
const wasm_hash = nativeToScVal(Buffer.from('d44487d42355ac978ddb16c28ac4672d91771e918bab07e2cc4c768e7f6fcee6'), {type: 'bytes'})

frank radish
#

Now the question is, why the wasm_hash is 64 bytes?
yes, it should be 32 bytes

#

so IDK why is it 64 b in your input

#

I'm not that familiar with JS SDK, so not sure what does buffer.from expect as the format

last ledge
#

Buffer.from is to convert a string to uint8array as bytes

#

Now d44487d42355ac978ddb16c28ac4672d91771e918bab07e2cc4c768e7f6fcee6 is the wasm_hash result from the CLI after isntalling the contract

#

How can we convert this hash d44487d42355ac978ddb16c28ac4672d91771e918bab07e2cc4c768e7f6fcee6 to 32 bytes?

That hash is in hex, so it is 64 characters, 64 bytes, and those 64 bytes in hex should map to 32 bytes binary.
