Prebuild logs are no longer being shown

[jankeromnes]

Bug description

When starting a manual prebuild, we used to get headless logs displayed.

However, since recently this is no longer the case.

Steps to reproduce

1. Start a manual prebuild for some repository, using the URL prefix gitpod.io/#prebuild/
2. No logs are displayed

Instead, the browser console shows errors like these in a loop:

/start: started workspace instance: da5c76e1-105d-4f0f-9efa-5731bb536500
Request getHeadlessLog unsuccessful: 404/"Headless logs for da5c76e1-105d-4f0f-9efa-5731bb536500 not found" 
Object { method: "getHeadlessLog", args: (2) […] }

Expected behavior

• The headless logs should get displayed
• No errors should be logged in the console

No response

Anything else?

I suspect (without proof) that this might be a recent regression caused by the deployment of this related PR: #4875

Interestingly, https://gitpod.io/#prebuild/https://gitlab.com/gitpod/spring-petclinic does show prebuild logs in prod:

/start: started workspace instance: e343d567-be7b-46ac-ac14-9498d4ca46e5
fetching from streamUrl: https://gitpod.io/headless-logs/e343d567-be7b-46ac-ac14-9498d4ca46e5/edb375c6-ae32-4fa3-96f0-2115bc19f07b

EDIT: And with https://github.com/jankeromnes/terraforming-mars-bot, the prebuilds work as well. I can no longer reproduce this issue 😕 will look more after lunch.

Dupe of #4856 (comment)

[csweichel]

Closing this issue for now. Let's revisit when it re-occurs. Also, we're looking at prebuilds and their logs in #4856
