running wdr.tools.exportApplicationManifestToFile produces error: AttributeError: getPolicySetAttachments

When running exportApplicationManifestToFile on an old WAS 6.1.0.47 I get the following output:
WASX7015E: Exception running command: "wdr.tools.exportApplicationManifestToFile('EnterpriseApp','/tmp/EnterpriseApp.deploy')"; exception information:
