Summary

We have some validation rules with line breaks, retrieve and deploy work so far, but when a flow hits this validation and should show the error, only an empty text is displayed. The default record page shows the original error message.

Steps To Reproduce

IMPORTANT Provide a repository that's configured to reproduce the issue. If you are unable to provide a repo, please explain why not. The more info we have from the start, the faster we can resolve your issue. We may close your issue if you don't include proper instructions.

Generate a project with sf project generate or fork dreamhouse-lwc.

Provide detailed step-by-step instructions on how to reproduce the issue.

Given:

Translations enabled
A validation rule with a multi line error message
No extra tranlsation for the given error message
A flow using an UpdateRecord that violates the constraint of the validation rule and shows Flow.FaultMessage on an error screen
All is deployed to another org using sf project retrieve start and sf project deploy start

Steps:

Run the flow and check the output of the FaulMessage
Edit the record using the default edit page and check the error message

[!TIP] use sf doctor --create-issue to automatically fill the required information

Expected result

The validation rule, the flow and the translation are properly part of the source package
After deployment the translation workbench does not show any translation for the error message
Both the flow and the standard edit page show the correct error message

Actual result

The object translation metadata file contains whitespaces surrounding the comment with the master error message
The translation workbench shows two whitespaces when editing the translation of the error message
The translation cannot be saved
The flow shows two whitespaces instead of the error message
