Error "TypeError: Argument 1 passed to Drupal\upgrade_status\DeprecationMessage::setFile() must be of the type string, null given"

Hi, I'm seeing the following error when scanning deprecation through both UI and Drush command

It looks like the file variable doesn't exist for the second if statement and thus causing the error.

The error is currently blocking deprecation scanning on module/theme library file with deprecated dependencies because the scanned result is now showing 500 error as problem instead of the actual deprecated issue.

I'm seeing the same error on both 3.x-dev and 3.0-beta2.

I haven't tested it on 2.x version yet.

Reproducible steps:

1. Go to any module/theme with `.libraries.yml` file
2. Change one of the dependencies of any library to a non-existing library

for example:

from

drupal:
  version: VERSION
  js:
    misc/drupal.js: { weight: -18 }
  dependencies:
    - core/drupalSettings

to

drupal:
  version: VERSION
  js:
    misc/drupal.js: { weight: -18 }
  dependencies:
    - foo/drupalSettings

Since the dependency "foo/drupalSettings" doesn't exist, it will be detected as a deprecation issue by this module.

3. Clear cache

4. Run the scan against the module/theme and you should see the error.
