I get this error on every web request rule and every rule activity in workflows after being imported and I don't understand the way it is phrased or how to fix it. The rules are published I can see them in the list I can select them. They have no errors.
The only thing I can do is replace the activities entirely and re-configure them from scratch.
Update: I think it has to do with the version of the rule used in the export not being a version that exists with the rule your using now. But in that case can't I just pick another version? Versions are almost never going to match with exports between repositories.
