@alexperovich It looks like whatever is processing the binlog needs to support a newer version. Can you take a look?

[ViktorHofer]

@MattGal that should be the corresponding issue: #7024.

[alexperovich]

I think this was hit by runtime a while ago, #7274 should fix this.

[ViktorHofer]

@alexperovich did you see #7024 which I filed some months ago?

[alexperovich]

I did, and it needs to be done, but it would involve adding arcade publishing to a repo that doesn't even know about arcade.

/azp run

[azure-pipelines]

Azure Pipelines successfully started running 1 pipeline(s).

[ViktorHofer]

I don't see the SDK change flowing into the repositories, i.e.: dotnet/runtime@9c39208. Is that intentional?

Blocked up here: https://github.com/dotnet/arcade-validation/pull/2268/checks?check_run_id=2449219260

[ViktorHofer]

Did you know about the pipeline being blocked? If not, would it make sense to monitor that repo via automation to notify in case something is blocked?

[mmitche]

I think it is monitored, just no one has gotten around to investigating the issue.
