Describe your issue

I'm running the prettier-plugin-apex in CI CD pipeline. Till version 2.1.4, everything is just fine but now in latest version 2.2.2. I'm getting some Internal error thrown by the plugin.

Though the plugin still scans and does it's job it seems but it keeps throwing error along.

I'm pasting the some portion of error log here due to length limitation for better understanding. Please find the complete log in the attached text file.

Hi there, thank you for reporting this issue. This is definitely very interesting, and I don't have a clear idea why it's happening just yet. Does this happen to only one file in your repository, or does it happen to every file?
If it's just one file, is it possible for you to send me that file so I can check the content?
Also, do you run into this issue locally or just in the CI/CD context?

On a technical note, reading the stack trace, it looks like the program is running into a stack overflow during the serialization process. I'm very curious how that could've happened.

One thing to try is to set the apexStandaloneParser config to none temporarily (guide here) to see if the root cause is from the native binary (introduced as the default parser in 2.2.0) or from some other causes.

This worked. Thanks!

It's happening to certain number of files but not all. I cannot share the exact file here but I'll try to get a similar class file where I can reproduce the issue. That should help you understand the problem better.

And yes, it's just happening in the context of CI/CD, working just fine on my local machine.
