Patch API Clarification

When using the patch API as the documentation instructed, it throws an error and wants to ask for multiple other fields. The other fields seem irrelevant to the field I am changing (IE Requires 'If you said other, specifiy your reasoning"). There are multiple errors for this operation and I want to know whether I am doing something wrong through my patch method (Is there something that needs to be added?) Or any additional context if someone has gotten a patch request for specifically a custom field to work.

Note - We have a solution which is able to patch files fine, its just setting a specific flag for that user as a means to help indicate usage.
