@Samuel_Tober: Hi! Since yesterday one of our flows has stopped running, it is marked as white in the UI (see screenshot). This is pretty urgent so it would be nice if I could get some quick help!

@Sylvain_HAZARD: What’s the state of those flow runs ?
@Samuel_Tober: I cannot even see the state. If i hover over a flow run i can only see the name of the run
@Sylvain_HAZARD: That’s really weird indeed. Are you running on Prefect Cloud or Server ?
@Samuel_Tober: Prefect cloud
@Sylvain_HAZARD: I’m sorry, I can’t think of anything that would cause this off the top of my head. You might have to contact the support directly or wait for a Prefect team member to answer here.
@Samuel_Tober: Works again now after rebuilding the flow
@Sylvain_HAZARD: Glad that it’s working again !
@Anna_Geller: @Samuel_Tober those white bars may indicate scheduled flow runs that had to be canceled by the Scheduler service due to new flow version. Any time you register a new flow version, the already scheduled flow runs for that flow version have to be cancelled - maybe that’s what was indicated by those white bars?
if you find more about that in a post-mortem, let us know
@Samuel_Tober: We did not create a new version recently so I cannot see how that would be the issue, but I will let you know if we would find the reason
@Anna_Geller: @Samuel_Tober and @Sylvain_HAZARD and anyone else stumbling upon this issue: the issue you see is a pure UI thing that happens when switching between light and dark mode! I’ve just found it out from our UI team.
So on the backend side everything should work as expected and no need to worry about the white bars - refreshing your screen should sort it out!
