Hi all!

I am trying to use the API to create assets in Eramba. I am using the following JSON:

{‘name’: ‘teste’, ‘description’: ‘teste2’, ‘asset\_label\_id’: 1, ‘asset\_media\_type\_id’: 1, ‘review’: ‘2023-11-14’, ‘created’: ‘2023-05-18’, ‘edited’: ‘2023-05-18’, ‘asset\_owners’: [‘Group-40’], ‘asset\_guardians’: [‘Group-40’], ‘asset\_users’: [‘Group-40’], ‘business\_units’: [9], ‘legals’: [7], ‘related\_assets’: [1], ‘asset\_classifications\_1’: [‘2 - Restrita’]}

however, I am receiving this error:

{“exception”:“ValidationException”,“message”:“8 validation errors occurred: asset\_owners.isArray - The provided value is invalid; business\_units.belongsToMany - This field cannot be left empty; business\_units.isArray - The provided value is invalid; related\_assets.isArray - The provided value is invalid; legals.isArray - The provided value is invalid; asset\_guardians.isArray - The provided value is invalid; asset\_users.isArray - The provided value is invalid; asset\_classifications\_1.isArray - The provided value is invalid; “,“url”:”/api/assets/add”,“error”:{},“code”:422}

Does anybody knows how can I send these fields?

If i copy paste your JSON to an online validator:

you are mixing up quote strings for sure, there might be something else. please use the documentation, we have an extensive library of examples.
