I have a K2 workflow associated to a SharePoint content type.  It had been deployed successfully before, but we're now needing to update it.

When running the msdeploy script, we get an error:

Error occurred associating workflow with content type.  Server did not recognize the value of HTTPHeader SOAP.

I triple checked the content type is still there, and hasn't changed.  I even removed the old workflow associated to it.  But same error.

Any ideas?
