getting Failed machine identity validation for table sys_import_set error

osmantaken1 · Friday

Hi Everyone,

I’m working on an eBonding integration using the Import Set API in ServiceNow and running into a Machine Identity Access Control issue.

Scenario

Created a custom staging table extending sys_import_set_row
Using Import Set API endpoint:
```
/api/now/import/<staging_table>
```
REST API Policy configured for:
- API Type = Import Set API
- All Resources = true
- All Methods = true
- All Versions = true
Integration user has roles such as:
- import_admin
- import_transformer
Machine Identity Access Control is enabled

What is happening

When Machine Identity Access Control is enabled, the API response returns:

{
  "error": {
    "message": "Action is not authorized",
    "detail": "Failed machine identity validation for table sys_import_set"
  },
  "status": "failure"
}

However, despite the error:

Records ARE successfully inserted into the staging table
Transform map executes successfully
Incident records are also getting created successfully

So functionally everything works, but the API response still returns the authorization error.

Additional observations

If I disable Machine Identity Access Control, the error disappears completely
I cannot see sys_import_set or sys_import_set_row available in the MIC resource selection list
This does not appear to be an ACL issue because inserts and transforms succeed successfully
The issue seems to happen during some internal Import Set API processing/validation step

Question

Has anyone faced this issue specifically with:

Import Set API
Machine Identity Access Control
Failed machine identity validation for table sys_import_set

Is there any additional configuration needed for internal import tables, or is this a known platform limitation/defect with MIC + Import Set API?

Any guidance would be appreciated. Thanks!
