Hi, I´m trying to create a work package from my custom form, I try to do it buy I always than have something on post body have that error:

I’m posting to the url /api/v3/projects/3/work_packages/form but same error on /api/v3/projects/3/work_packages

errorIdentifier: "urn:openproject-org:api:v3:errors:InternalServerError" message: "An internal error has occured." _type: "Error"

},
project
href
},
“type”:
{

},
