[regression] Fix error on no MIME type

[MegaphoneJon]

I have a regression from #16436. It's in my logs, so I don't know how to replicate it, but it seems easy to fix.

Since upgrading to 5.25.0 I've been seeing this error:

TypeError: Argument 1 passed to MimeTyper\Repository\AbstractRepository::setFromMap() must be of the type array, null given, called in /var/local/mysite.org/sites/all/modules/civicrm/vendor/adrienrn/php-mimetyper/src/Repository/MimeDbRepository.php on line 52 in MimeTyper\Repository\AbstractRepository->setFromMap() (line 18 of /var/local/mysite.org/sites/all/modules/civicrm/vendor/adrienrn/php-mimetyper/src/Repository/AbstractRepository.php

Change seems fine to me merging

@seamuslee001 - I'm still seeing this in 5.27.5 ESR - even though it looks like this fix went into 5.26?

TypeError: Argument 1 passed to MimeTyper\Repository\AbstractRepository::setFromMap() must be of the type array, null given, called in /sites/all/modules/civicrm/vendor/adrienrn/php-mimetyper/src/Repository/MimeDbRepository.php on line 52 in MimeTyper\Repository\AbstractRepository->setFromMap() (line 18 of /sites/all/modules/civicrm/vendor/adrienrn/php-mimetyper/src/Repository/AbstractRepository.php).

Just noting that we also saw this issue in 5.27.7.

Notes from our development team:

At location ' /sites/all/modules/civicrm/vendor/adrienrn/php-mimetyper/ ' there must be a file ' /node_modules/mime-db/db.json' present. However in the .gitignore CiviCRM has ignored the '/node_module' directory. So due this ignore this db.json file was not pushed & it was missing on server. So we just pushed it on server and removed the entry from .gitignore

@bryan-skvare That's correct. That same fix is in Civi 5.31: #18673
