I just encounted the exact same error.

Cause

After setting the system.debug variable to true, it revealed that the publish task actually performs a zip of the output folder (which by default is $(build.artifactstagingdirectory)) and places this 1 level higher in the directory structure. It then proceeds to delete the actual folder itself! I'm not sure if this is intended at all or a bug.

Workaround

After observing the above, I simply had the output of the publish task write to $(build.artifactstagingdirectory)\artifact and the resulting Publish Artifact task was then happy to pick up the zip file as it was still pointing to $(build.artifactstagingdirectory)

Default Publish Task output that fails
