[Bug]: StringMap not found

[daveHT]

What happened?

When I try to follow the tutorial for the basic set up I'm getting an internal error

include(StringMap.php): Failed to open stream: No such file or directory

Note that the code from the tutorial works totally fine (I am able to create the StringMap and dispatch the notification) as per the snippet below

function createNotification($enContent): Notification { $content = new StringMap(); $content->setEn($enContent); $notification = new Notification(); $notification->setAppId(APP_ID); $notification->setContents($content); $notification->setIncludedSegments(['Subscribed Users']); return $notification; }

The error is happening deep inside the OneSignal SDK code inside ObjectSerializer.php.
vendor/onesignal/onesignal-php-api/lib/ObjectSerializer.php(93): is_callable()

The call to is_callable() is failing (can't find StringMap).

Interestingly I have no problems including and creating my own StringMaps (along with other OneSignal types) so it's not a dependency issue that I can see. (I'm not ruling out an issue with my composer setup but all else seems to be working).

In ObjectSerializer.php there one line before the offending line there is long list of allowable types that it checks that skip the call to is_callable(). I added StringMap to that list, and everything works perfectly after that. Obviously this solution is a bit of a hack, but it's interesting that everything works after I do that small change (I can get notifications to show up on devices and there are no errors).

if ($value !== null && !in_array($openAPIType, ['\DateTime', '\SplFileObject', 'array', 'bool', 'boolean', 'byte', 'double', 'float', 'int', 'integer', 'mixed', 'number', 'object', 'string', 'void', 'StringMap'], true)) { $callable = [$openAPIType, 'getAllowableEnumValues']; if (is_callable($callable)) { ......

I talked to support and they advised that they are forwarding to the dev team but also said that I should post here to understand what is happening and see whether this is a bug or issue with my setup.

Thanks!
