Background agent fails to boot

Support Help

I went through the Background Agent/VM setup wizard to preinstall my dependencies. The Snapshot works fine when running cloud agents from the Cursor IDE, but when I start them from the Cursor Agents Web I get

Agent encountered an error

We encountered an unexpected error repeatedly.

You can retry by writing a follow-up below.

Working one from IDE: bc-98727be5-af6f-406c-ac70-7ccade54db8b

When I try to open the failed one locally, I only see this

And there is no “Open VM” option I can use to debug further.

Is there any way to get a better error message?

Note that if I start the config wizard again, it is able to boot from that snapshot and my deps are there… so it really seems to fail ONLY when booted from the Cursor Agents Web (which is where I wanted to use it haha).

This includes Slack and Github originated agents.

hi @alexandrosandre can you check if the environment.json on GitHub is the same you have on your local machine?

Its the most likely cause if it works in IDE and not in Web/Slack.

Totally! Agent had put some placeholder value instead of the real snapshot ID!

Well caught. Thank you!
