Describe the bug

Upgraded to v4.16.14 and encountered the following error:

[web] | 2026-04-23T16:09:55.758Z error: [sew] Error: EACCES: permission denied, stat '/data/.sourcebot/repos/131' {"task":{"commands":[],"format":"empty"}}
[web] | Error: Error: EACCES: permission denied, stat '/data/.sourcebot/repos/131'

[web] |     at z.attemptTask (/app/packages/web/.next/server/chunks/_08l9pj1._.js:2:15536)

Downgraded to v4.16.13 and errors went away...

Looks like my changes in #1104 caused an unintended breakage.

Confirmed by Sourcebot - https://app.sourcebot.dev/chat/cmobokddf0075k36xu33uu022
