OAuth2: No creation / sync of TYPO3 forms with Mautic

[mdlrvie]

I have experienced a problem upgrading an existion system from OAuth1 to OAuth2. OAuth1 is working just fine. But not in OAuth2.By saving a form in TYPO3 Backend, the sync starts, but Mautic shows an error in log (and also by using the form in TYPO3-Frontend):

mautic.CRITICAL: Uncaught PHP Exception OAuth2\OAuth2AuthenticateException: "invalid_request" at /var/www/html/mautic/vendor/friendsofsymfony/oauth2-php/lib/OAuth2.php line 517 {"exception":"[object] (OAuth2\OAuth2AuthenticateException(code: 0): invalid_request at /var/www/html/mautic/vendor/friendsofsymfony/oauth2-php/lib/OAuth2.php:517)"} []

Therefore no form or any fields are created in Mautic.
All the other features like sync of Segments, Tags, ... work quite well.

Systems:

• TYPO3 10.4.23
• mautic-typo3 plugin 4.1.0
• Mautic 3 and 4 (only oAuth2)

Hi @mdlrvie. I have looked into this issue and was able reproduce it, thus confirming this bug.
We will further investigate what causes this issue and will provide a fix as soon as possible.

For now you can just use a standalone form und use the common procedure of copying the JS to paste your form onto your page.

@mdlrvie Would you be able to check if this issue still exists in the current v4.3.1?
