Troubleshooting RPA bot generation in IBM Process Mining

Use these solutions to resolve common problems that you might encounter with RPA bot generation in IBM Process Mining.

Error message that is related to bot generation timeout

This issue occurs when the script continues to run longer than the defined maximum amount of time defined in the generator script.

Symptom

In the tenant-level configuration, you can set a time frame in the Pluggable RPA bot Generator Timeout (seconds) field and define the maximum amount of time the generator script must run. If the script continues to run after the defined duration, then the system automatically stops the process.

Workaround

Do the following steps to increase the value defined for timeout:

  1. In IBM Process Mining, go to Administration > Tenants, and then click Edit to change the value for the selected tenant.

  2. In the Pluggable RPA bot Generator Timeout (seconds) field type the new time frame.

  3. Save the changes.

Error in creating RPA bot

This error occurs when the uploaded pluggable RPA bot generator script has issues or defects, for example a syntax error. The error message provides a detailed description and the line numbers in which the defect was observed.

Symptom

A notification with the detailed information about the error shows up in the RPA Candidates window.

Workaround

To resolve this error, review the uploaded pluggable script file of the RPA bot generator to make the necessary changes at the line numbers mentioned in the error notification.

BPMN Data model contains no start nodes

This error occurs when the BPMN model of the project does not contain a single start node.

Symptom

A notification with the detailed information about the error shows up in the RPA Candidates window.

Workaround

An ideal BPMN model of the project must have a single start node and one or more final nodes. To resolve this error, verify and update the project configurations.

BPMN data model contains more than one start node

This error occurs when the BPMN model of the project contains multiple start nodes.

Symptom

A notification with the detailed information about the error shows up in the RPA Candidates window.

Workaround

An ideal BPMN model of the project must have a single start node and one or more final nodes. To resolve this error, verify and update the project configurations.

BPMN data model contains no end nodes

This error occurs when the BPMN model of the project does not contain a single final node.

Symptom

A notification with the detailed information about the error shows up in the RPA Candidates window.

Workaround

An ideal BPMN model of the project must have a single start node and one or more final nodes. To resolve this error, verify and update the project configurations.

Viewing the error logs and stacktrace of a custom RPA bot generator

This error occurs due to communication issues with task mining service. For example, you incorrectly configured the service and SSL hand-shake issues happen.

Workaround

When you run the custom RPA bot generator and an unexpected error occurs check the displayed errors. If no major error shows, verify the error logs and stacktrace to accurately identify the issue. For non-containerized on-premises installations on Linux, go to the following locations on the Process Mining server to check the files:
  • /opt/processmining/repository/logs/pm-web.log
  • /opt/processmining/repository/logs/engine.log

Bot generation encountered an error

This error occurs when you receive an error notification during the generation process.

Symptom

A notification with the detailed information about the error shows up in the RPA Candidates window.

Workaround

As a first step, verify whether any specific reasons are provided in the error message. If no specific reason is displayed in the error message, then you need to verify the server logs to identify the issue.
