Thanks, that has been broken a while, I wonder which action is best though, publish only compiles and publishes, but we don't run the pr validation one on main after merge, the nightlies perhaps, but those has the multi node cluster tests which are a bit unstable so it would show non-passing more often than not. Hmmm.

[akirataguchi115]

we can also think about what we want to achieve with the build badge on top of the README

[johanandren]

Yeah, good point, maybe we should just drop it.

[akirataguchi115]

sure if it makes the most sense! just lmk if i should remove the badge in this pr

[johanandren]

Let's drop it, feel free to do it in this PR or we can do it ourselves and close this PR.
