Still facing same issue . i try with sudo composer update and its update version to 4.23.1(nelmio/api-doc-bundle) but then also its show same error

[DjordyKoert]

Do you also have this issue with the latest version?

[DipenAVDEVS]

Yes , when i try with composer update its update to 4.23 and show me same error.

[bobvandevijver]

I'm seeing this when I override the type with JMS to enforce a backed enum to be serialized with its name. This looks as follows:

#[Type('enum<' . ActiveCampaignListStatusEnum::class .', name>')]

This is caused due to the type not being just a string, but an array:

https://github.com/nelmio/NelmioApiDocBundle/blame/9b91d2376888c2dacf4192b103a7ff7f67112bf5/src/ModelDescriber/JMSModelDescriber.php#L331

So, it looks like this:

As that comes from JMS and is handled in JMS correctly, I believe it should be handled here as well. PR incoming!

[bobvandevijver]

It is only partly handled in JMS, because for this particular type annotation you apparently are required to wrap the type with quotes. So, for the example above it should become:

#[Type('enum<\'' . ActiveCampaignListStatusEnum::class .'\', 'name'>')]
or
#[Type("enum<'". ActiveCampaignListStatusEnum::class . "', 'name'>')]

Then it works as it should. Another PR will be made at JMS to solve this inconsistency.
