Appears related to this Github issue.

Mautic creates additional custom fields as columns in the leads table, and MySQL imposes a limit on how many columns or bytes of data there can be in a particular row. Wonder if upgrading to MySQL 8.0 from MySQL 5.7 would expand the number of columns possible.

There is an extended field plugin that is mentioned in this linked issue, which may help for your particular use case.

We’re exploring Mautic as a solution and would also require a fair amount of custom fields for our purposes. Have you tried the plugin that was mentioned and did you have success with it?

I’ve tried the plugin. I added around 300 custom fields, didn’t test it extensively, but so far so good
