Hi,

I’m facing an issue with a custom Jira agent where it is unable to read or fetch attachment details, even though the same attachment is successfully accessed by Rovo.

Issue Details

When my custom agent tries to fetch an attachment using the Jira REST API, it fails with a 403 – Access Forbidden error.

What Works

✅ Rovo can:

• Read the attachment
• Fetch attachment details and content

❌ Custom agent(My agent ):

• Fails with 403
• Cannot hydrate the attachment URL

Questions / Help Needed

1. What permissions or scopes are required for a custom agent to access Jira attachments?
2. Is there a difference in authentication, internal privileges, or service accounts used by Rovo vs custom agents?
3. Are there any additional headers, OAuth scopes, or API restrictions that apply specifically to attachment APIs?
4. Is this a known limitation for custom agents?

Any guidance or documentation pointers would be really helpful.

Thanks in advance
