Errors from po reader are not shown anywhere

Have not seen any errors during import of translations? Wonder if this is still an issue in D10?

I ran into this on a Drupal 10.3 site. From what I see in the 11.x code, it is still an issue.

For me, the specific issue is that in locale.bulk.inc, exceptions caught in locale_translate_batch_import() log only generic messages.

To replicate:

1. Create a .po file with an error it. I have attached an example.

2. Create a site with the language for the .po file enabled.

3. Attempt to import the .po file at /admin/config/regional/translate/import.

4. See the error, "One translation file could not be imported. See the log for details."

5. See log, no details are included.

What I expect to happen:

Specific error messages are logged. In this case, "The plural formula could not be parsed."

Next steps

The patch in this issue wouldn't apply; it calls watchdog() instead of \Drupal::logger().

I don't see any other places in locale.bulk.inc where a specific error message isn't logged, but I may have missed something and there may be other places in the module.

A simple way to address this is to assign the Exception to a variable and include $e->getMessage() in the log.

I'm happy to do more work on this at the maintainers' direction.

Have not reviewed yet but issue summary appears to be incomplete, recommend using standard template for that. May need test coverage as well.

I erred on the side of contributing to an existing issue. Would you rather I open a new one?
