The update 1.27 of the docker plugin seems to have introduced a blocking issue.

When starting a container like so:

docker.withServer(env.DOCKER_HOST, env.DOCKER_HOST_CREDS) {
  docker.image(imageId) {
    …
  }
}

I'm getting the follow message in the log when using 1.27:

C:\Temp\jenkins_ws\…\15>docker inspect -f . "$JD_TO_RUN" 

Error: No such object: $JD_TO_RUN

After the downgrade to 1.26 im getting:

C:\Temp\jenkins_ws\…\16>docker inspect -f . mcr.microsoft.com/powershell:lts-nanoserver-1809
.
