Issue
After upgrading to RSA Identity Governance and Lifecycle 7.0.2 P05, emails from the approval and fulfillment nodes do not get generated and sent for a few of the workflows due to the following error:
URLDecoder: Illegal hex characters in escape (%) pattern - For input string: "; "
You will find the error below in the aveksaServer.log:
ERROR (Worker_actionq#Script Queue - Normal#WPDS_279) [com.aveksa.server.workflow.scripts.nodes.SendEmailThread] Couldn't Send Email to due to: java.lang.IllegalArgumentException: URLDecoder: Illegal hex characters in escape (%) pattern - For input string: "; " at java.net.URLDecoder.decode(URLDecoder.java:192) at com.aveksa.server.workflow.scripts.nodes.SendEmailThread.getBody(SendEmailThread.java:109) at com.aveksa.server.workflow.scripts.nodes.SendEmailThread.sendEmail(SendEmailThread.java:146) at com.aveksa.server.workflow.scripts.nodes.SendEmailThread.sendEmail(SendEmailThread.java:66) at com.aveksa.server.workflow.scripts.nodes.SendEmailThread.run(SendEmailThread.java:62)
This error is similar to the error seen when the email node contains a percent (%) character as described in article 000036165 - After patching to RSA Identity Governance & Lifecycle 7.0.2 P03+, emails are not generated and sent due to the error 'Illegal hex characters in escape (%) pattern', but the cause is not similar.
Here, the issue is seen even if the email body does not contain any % characters.
Cause
Another cause for the email not being sent is due to a NullPointerException when either Workflow Variable or Object Attribute is added in the Send Email node.
Resolution
Workaround
- Save the workflow node which is not generating emails again, or
- Recreate the node after deleting the node which is having issue.
