DRAFT KB-[SP-7316] Package import fails with missing precedent error on node output

Symptoms

Package imports containing a process model fail with an error similar to below:

The processModel [id=<PMUUID>] was not imported because a required precedent is missing: content [uuid=0000cf6b-c49b-8000-6c30-0a000064055c location=Node > "<NodeName>" > Node Output] cannot be found.

Searching by UUID or ID for this missing precedent additionally returns no results.

Cause

A process variable is being identified as a missing precedent, usually when the process variable has the same name as a constant that does or used to exist in the environment. This issue has been reported to the Appian Product Team. The reference number for this issue is AN-196715.

Workaround

1. If not installed, install the Content Tools Plug-in from the App Market.
2. In an empty expression rule run getcontentdetailsbyuuid(objectUUID:"<UUID>"). The result value should be a constant name, such as cons!<NameOfProcessVariableInAffectedPM>
3. Rename the conflicting process variable in the affected process model to a different value. Ensure references to this process variable are updated as well.
4. Re-perform the import. There should be no missing precedent error at this point.

Affected Versions

This article applies to all versions of Appian 21.2 or later.
