Lost validator traces

[rober-m]

When I evaluate (utils/tx/evaluate or utilsTxEvaluate()) a validator compiled with traces, I get the generic:

evaluateTx with blockfrost-js:  {
  type: 'jsonwsp/response',
  version: '1.0',
  servicename: 'ogmios',
  methodname: 'EvaluateTx',
  result: { EvaluationFailure: { ScriptFailures: {} } },
  reflection: { id: '46a98ded-f249-41a1-a322-48533a3cc670' }
}

As you can see, ScriptFailures is an empty object, but Ogmios does return the traces. Why isn't this working?

I'll look into this. Could you please provide the transaction CBOR?

Thank you, @vladimirvolek, for the prompt response! I simplified the Tx to avoid clutter.

txHex:

585601010032323232322533300232323232324a26012601400460100026010004600c00260086ea8004526153300349011856616c696461746f722072657475726e65642066616c736500136565734ae7155cf2ba157441

evaluateTx with blockfrost-js:

{
  type: 'jsonwsp/response',
  version: '1.0',
  servicename: 'ogmios',
  methodname: 'EvaluateTx',
  result: { EvaluationFailure: { ScriptFailures: {} } },
  reflection: { id: '327042ca-bc80-4946-af25-fa15c3767147' }
}

And this is the validator's source code (aiken v1.1.0+5879dcf).
Compiled with aiken build --trace-level verbose --filter-traces all and checked the wc to see if traces are actually maintained after compilation

validator burn {
  else(_) {
    trace @"this is a trace message"
    trace @"this is another trace message"
    False
  }
}

Okay, I found and fixed the problem. I will let you know when it's deployed to production here.

Awesome, thank you so much!! 🙌

Hi, @vladimirvolek! It seems it didn't work. 😕 I'm still getting the same response (same Tx, same setup):

evaluateTx with blockfrost-js:  {
  type: 'jsonwsp/response',
  version: '1.0',
  servicename: 'ogmios',
  methodname: 'EvaluateTx',
  result: { EvaluationFailure: { ScriptFailures: {} } },
  reflection: { id: 'd04605d5-6582-47a5-955d-7e58a8f3d774' }
}

[vladimirvolek]

ohh what.. let me check

[vladimirvolek]

That's strange. Could you please provide a full example of the payload you're sending? Thanks!

[rober-m]

Hi @vladimirvolek! Here's a repo with a full example to reproduce the issue

Hi, @vladimirvolek! Sorry for bothering but is there any news on this? 🙏

[rober-m]

Pleeeeeeeeease 🙏

[vladimirvolek]

Alright, I have a bit more time now. Thanks for your patience with the delay.
