Hello,

We've recently upgraded to the Invision v2.7.0 and changed our PHP version to 8.1 which is supported now. After this change we see some errors coming from the profilesync maintenance task not being able to run due to errors. Our logs go back one week and this error started after the upgrade, prior it was not causing issues.

The errors are:

TypeError: array_key_exists(): Argument #2 ($array) must be of type array, null given (0)
#0 /var/www/html/public/system/Login/Handler/OAuth2/Custom.php(472): array_key_exists()

I've looked through the code, and tried to call our custom OAuth2 provider with Postman and with an access token, and it returns the data in an array as expected. My hypothesis is that something is broken or a check is missing perhaps for users with expired access tokens? Perhaps PHP 8 changed some argument requirements in some of the functions?

Before we look further into this, could you confirm if you have checked this already on your previous PHP version?

I changed PHP version to 7.4 and the maintenance task ran successfully, so seems to be a PHP 8.1 issue indeed.

Please be advised I have tagged this to a developer to review and confirm.

Hello, any updates on this potential issue?

There is no update for this at the present time, however it has been tagged for developers

Please could I ask that you test this again on the latest release? Once you have checked this, let us know the result. If you are still having issues, I will then get a bug report opened for you

Hi again, I've tested again and still experiencing the issue:

Invision Version 4.7.2.1
PHP 8.1.10

Stupid question … does this happen in php 7.4?  I’m wondering if this is a php 8/8.1 issue.

It's only happening in PHP 8.1 for me. 7.4 does not have this issue.

I have created a ticket for you on this. Please ensure you access details are up to date, and that your site is currently running 8.1 so we can see the issue

Hi @Marc Stridgen

Replying here as it seems the email-reply on the ticket was not accepted.

 

We seen that latest December update seems to perhaps attempted a fix? We'd like to share the issue still persists. The fix is to ask the OAuth source for a json response with [["Accept" => "application/json"]]. 

 

If the December update was not meant to fix this yet, is there any estimate for a fix? We'd love to avoid uploading our workaround of this issue for each update 🙂

Sorry, this was not in the December release but hopefully will be in our next release which will be in February or March at this point due to all the holidays here.
