make:entity fails: In DoctrineHelper.php line 314: Warning: Invalid argument supplied for foreach()

[SieGeL2k16]

I've tried to create a new entity in an existing project.
Called the command make:entity, entered the name of the new Entity and right after this got the following warning:

bin/console make:entity

 Class name of the entity to create or update (e.g. TinyChef):
> EsserFiles


In DoctrineHelper.php line 314:
                                                    
  Warning: Invalid argument supplied for foreach()  
                                                    

make:entity [-a|--api-resource] [-b|--broadcast] [--regenerate] [--overwrite] [--] [<name>]

I've checked the DoctrineHelper.php @ line 314 and the foreach() Parameter $this->mappingDriversByPrefix is NULL.

As a workaround I've added a check if $this->mappingDriversByPrefix is not null and the make:entity is working.

However I'm not sure if this is the desired behavour.

Hmm. Can you post your versions of doctrine/doctrine-bundle, doctrine/orm and doctrine/dbal? This behavior is related to those versions... so it could be some problem specific to a version mix you have. Regardless, it certainly looks like a bug.

@weaverryan Here it goes:

doctrine/doctrine-bundle 2.1.2
doctrine/orm 2.10.1
doctrine/dbal 2.13.4

Just tried this with PHP 8.0.11 (my original post was tested with PHP 7.4.24), and got almost the same error:

bin/console make:entity

 Class name of the entity to create or update (e.g. DeliciousPuppy):
 > TestSascha


In DoctrineHelper.php line 314:

  Warning: foreach() argument must be of type array|object, null given

[weaverryan]

Hmm, ok my guess is that we have a bug in DoctrineBundle LESS than 2.3 & MakerBundle 1.34.0, because we modified this behavior in that release: 9ecc684#diff-ac3a9e6886ce5b8d1d6a3742fa169ee859a8a140d1bbf8a03f1a56335607ade6

[weaverryan]

fixed in #993

Just checked again after doing a composer update and make:entity is now working, thanks for fixing!
