Failed to unmarshal rdjson on version 1.20.0

[taltcher]

After upgrading to version 1.20.0 we have started to receive:

reviewdog: parse error: failed to unmarshal rdjson (DiagnosticResult): proto: syntax error (line 2:1): unexpected token

Can you work on it? @bert-mccutchen

[bert-mccutchen]

Yep , @taltcher do you have a full stack trace?

Ok so the error seems to stem from Stylelint failing to run. @taltcher is there any error printed to your logs from Stylelint prior to Reviewdog attempting to run, that would be helpful for debugging.

Hi @bert-mccutchen -
This is the full error that I'm seen:

  TypeError: Cannot read properties of undefined (reading 'CssSyntaxError')

Which logs do you want me to find?

[bert-mccutchen]

Ahh, that's actually perfect, thank you.

Hey, I am not sure if it is the same problem, but I didn't want to create a new issue in case it is.

I am getting this in the Github action log (with debug enabled):

@th0th is that pre-1.20.1 release or post-1.20.1 release?

[th0th]

I get this with uses: reviewdog/[email protected].

[bert-mccutchen]

@th0th you don't by any chance happen to be using Stylelint 16, eh?

Ignore me, I see the stylelint version: [16] hidden in that wall of text.

Hi @haya14busa @bert-mccutchen - seems like there is still an issue... Tried to run the action with the updated version - and receive the next error:

  reviewdog: parse error: failed to unmarshal rdjson (DiagnosticResult): proto: syntax error (line 1:4259): invalid escape code "\\." in string

I don't see know any stackstrace... Just this error

Hi all, any progress or time estimate for a fix here? We're facing the same issue.
