Custom connector issue

Hi,

we are developing a custom connector for a custom platform. Specifically, the connector should make an http PATCH call to the target.
The parser however does not accept the patch method, returning the following error: Platform definition is not valid JSON: Error converting value "PATCH" to type 'Hercules.Modules.Scriptable.support.Http.RequestVerb'. Path 'Do[5].request.Verb', line 208, 25.
How do you suggest we proceed?

Thank you,
Elena
