Error - "ACL Exception Insert Failed due to security constraints"

[shubham23]

Hi,

I am trying to upload an attachment in the incident table using API. But I am getting below error:

status: failure
The remote server returned an error: (403) Forbidden.
message: Operation Failed
detail: ACL Exception Insert Failed due to security constraints

I am using non-admin user and don't know which ACL rules operation should be applied to which table. So, that user can upload the attachments

Could anyone please help me ?.

Thanks!

These links should help you debug:

Have you customized any of the Out-of-Box (OOB) ACL rules or created your own?

Does the syslog provide any more detail for the specific ACL that fails?

Have you looked at the "Attachment API" with the "REST Endpoint" type? It is not active on my instance but it might be on yours.

Working:
Added below ACL and now able to upload the attachment:

• sys_attachment_doc (create)
• sys_attachment (create)
• ecc_queue (create)

For Downloading attachment provided below ACL:

• sys_attachment_doc (read)
• sys_attachment (read)
• ecc_queue (read)
