It is working fine with empty value of “part_of”:"", but doesn’t work while I pass value for part_of. part_of is basically a parent company which I am trying to create. so my expectation is create a company(part_of) first, get it’s id and make that id as foreign key for another company. Anyone implemented similar to this? Or what I am doing wrong here, suggestions, help is appreciated. Thanks in advance.
The error I am getting is:
“part_of”: [
"“{ ‘name’: ‘Parent of Organization’, ‘telecom’: [{‘system’: ‘phone’, ‘value’: ‘677-7777’}, {‘system’: ‘email’, ‘value’: ‘[email protected]’}], ‘address’: [{‘line’: [‘3300 Washtenaw Avenue, Suite 227’], ‘city’: ‘Amherst’, ‘state’: ‘MA’, ‘postalCode’: ‘01002’, ‘country’: ‘USA’}]}” is not a valid UUID."
