Your software
My Mautic version is: 4.4.6
My PHP version is: 7.4.33
My Database type and version is: MySQL 8

Your problem
My problem is:

I am using the Mautic PHP library as recommended in the docs.

I am able to successfully create and edit contacts using the API (basic auth).

When attempting to update the contact by updating custom fields & applying tags or removing tags I sometimes receive a success response from Mautic but when I attempt to view the in Mautic I get a 500 error.

Unfortunately when checking the /var/logs folder and viewing the files there are no details regarding this error at all.

Really hoping for some insight :slight_smile:

You can clear the mautic cache and then try again, and make sure update all fields value correctly for example don’t put string value in multiselect field, that is not mapped in that multiselect field values.

The Mautic team has confirmed the bug on the github repo so theoretically it’s being taken care of there :slight_smile:
