This issue has been resolved in an Appian hotfix/new Appian version. Please apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.

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=<UUID> location=Node > "<NodeName>" > Node Output] cannot be found.

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

Cause

This issue has been addressed via AN-196715 in the following hotfixes:

21.2.850.0
21.3.605.0
21.4.340.0

Action

Apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.

Workaround

If not already installed, deploy the Content Tools Plug-in from the App Market.
Create a new expression rule with the following contents:
getcontentdetailsbyuuid(objectUUID:"<UUID>").
Execute the expression rule. The result value should be a constant name, such as cons!<NameOfProcessVariableInAffectedPM>
Rename the conflicting process variable in the affected process model to a different value. Ensure references to this process variable are updated as well.
Retry the import. There should be no missing precedent error at this point.

Affected Versions

This article applies Appian versions 21.2, 21.3 and 21.4.

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.

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.

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

Symptoms

This section is required for this template. All symptoms of the issue, including relevant screenshots and log lines, should be included here. The symptoms should be as descriptive as possible.

Cause

This section is required for this template. When writing a cause for a particular article, ensure the following is taken into consideration:

The cause is concise and does not disclose more information than absolutely necessary.
The cause does not share any Appian source code. Source code for plugins/shared components are fine.
If this is an issue outside of the Appian product and the third-party vendor included documentation referencing the bug, provide their documentation for reference.

For any enhancements/defects, use one of the following as applicable:

This issue has been reported to the Appian Product Team. The reference number for this issue is AN-XXXXX.
This product use case has been logged to the Appian Product Team for consideration to add this functionality in the product. Kindly note it is not Appian Support’s policy to disclose how or when a product use case will be implemented.
This issue has been hotfixed via AN-XXXXX in Appian X.X.
This issue has been hotfixed via AN-XXXXX in Appian versions X.X to X.X.
This use case has been incorporated in Appian X.X.
This use case has been incorporated in Appian versions X.X to X.X.

When logging a product defect, ensure you use the known issues tag as well as the open issues or fixed issues tag, depending if the issue is fixed or not.

If no cause is known and this is not something Engineering can reproduce/needs to know about, then say “The root cause of this issue is currently unknown.” If you use that as your cause, then a valid action must be present.

Action

This section is required for this template and contains the steps to resolve the issue. If an issue in an article is solved by a hotfix and/or major version of Appian, use the following language to indicate that:

Apply the latest hotfix to your Appian installation.
Upgrade to the latest version of Appian.
Apply the latest hotfix to your Appian installation or upgrade to the latest version of Appian.

If there is a product issue with Engineering that is open and a workaround for that issue exists, include it in the Action section until the fix is available. After the fix is made available, use that as a workaround instead.

Otherwise, the content in this section should wholly solve a customer’s issue without producing any undesirable side effects. If there is at least one valid action that doesn’t cause undesirable side effects, all other actions with negative side effects should go in the Workaround section.

If there is no action or workaround that resolves the issue, use the following language:

There is no action or workaround currently available for this issue. If you are facing this issue, please open a support case with Appian.

Workaround

If not installed, install the Content Tools Plug-in from the App Market.
In an empty expression rule run getcontentdetailsbyuuid(objectUUID:"<UUID>"). The result value should be a process variable used in the affected process model, but as a constant. EX. cons!<ProcessVariable>
Rename the conflicting process variable to a different value. Ensure references to this process variable are updated as well.
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.
