Fly set-pipeline returning no changes to apply

When trying to set a new pipeline i’m getting “no changes to apply” messages. and i’m sure i don’t have any pipelines with the same name. In fact i tried it in a brand new team which i just created.
Concourse version: 5.4.1 and 5.7.1 yes, i have both the versions.

It could be that there’s yaml errors in the pipeline that are making Concourse ignore most of it. When I try setting a pipeline with a yaml file that isn’t actually a pipeline I get the no changes to apply message.

Thanks for the reply, in my case the pipeline is correct with no errors. Just a system restart worked. Don’t know the actual reason.
