I want to test a class with an invocable method. Actually i get 51% Coverage and  at the line 73 in the Test class the error is:

"System.DmlException: Update failed. First exception on row 0 with id a03f0000006BbNwAAK; first error: CANNOT_EXECUTE_FLOW_TRIGGER, We can't save this record because the “Post Affiliate Inventory” process failed. Give your Salesforce admin these details. An Apex error occurred: System.DmlException: Insert failed. First exception on row 0; first error: INVALID_CROSS_REFERENCE_KEY, Record Type ID: this ID value isn't valid for the user: : [RecordTypeId]
: []

I want to remind that this class is to copy all child records from an object to an other object when a criteria is meet in the parent record.
