To Reproduce Run a BLT (13.5.3) build through Code Studio to deploy to Acquia Cloud. CI/CD fails at deploy step.

Expected behavior Deploy successfully occurs.

Detailed error output See above.

BLT doctor output Cannot acquire since it is inside the CI/CD env.

System information

• Operating system type: Acquia Code Studio
• Operating system version: N/A
• BLT version: 13.5.3

[fiasco]

This function is present in the latest version of composer/xdebughandler which suggests Code Studio isn't up to date.

@fiasco are you running the stock code studio build, or did you end up customizing yours? i haven't seen this failure.
