Incident Closure via REST API Fails with "Cause code" Mandatory Data Policy Exception

[meena eethakatl]

Hi Team,

We are facing an issue while resolving Incidents through the ServiceNow Table API.

When updating an Incident to the Resolved state via a REST API PUT request,

we receive the following error:

{

"error": {

"message": "Operation Failed",

"detail": "Data Policy Exception: The following fields are mandatory: Cause code"

},

"status": "failure"

}

reuqets payload - 

{

"work_notes": "testing",

"incident_state": "6",

"close_code": "Solved",

"close_notes": "testing",

"u_cause_code": "Application - Caused by Change",

"u_solution": "resolved"

}

Observations:

• The Cause Code field is being passed in the API payload.
• The Incident can be resolved successfully from the UI.
• The issue occu
• rs only when resolving through the REST API.
• A Data Policy is enforcing Cause Code as mandatory.

how to fix it

Validate that the cause code you are sending is correct. From the looks of it, it's a custom field, so not sure if it's a string or a choice field. If it's a choice field, make sure it's the correct VALUE of the choice (not the LABEL).

Yes, u_cause_code is a choice field, and we are passing a valid value in the API payload. However, the value is not being updated in ServiceNow, and we continue to receive a Data Policy Exception stating that Cause Code is mandatory. how to fit it

As mentioned by Mark, please validate the choice value in the payload you are sending

Please let us know if that resolves the issue
