JIRA SOAP: Error message: [Could not load validator class] for progressWorkflowAction

I am using JIRA's SOAP API to change defect's status by jumping from one status to another and everything was fine until I need to jump on "verified" status where user needs to enter some text into textbox field.

I am using progressWorkflowAction method and at attempt to jump to this status I am getting an exception:

com.atlassian.jira.rpc.exception.RemoteException: Error occurred when running workflow
action To Verified: 
Errors: {}
Error Messages: [Could not load validator class]

Any ideas how can I specify this text which is required for this workflow element?

p.s: Have tried this: 

JiraClient.progressWorkflowAction(token, "DEF-5", "171", new RemoteFieldValue[] { new RemoteFieldValue { id = "customfield_10175", values = new string[] { "test" } } });
Solution

  • First, try to install JIRA Suite Utilities plugin (source) according to your Jira version. This is probably the reason for this error.

    If it doesn't help, have a look at Cannot Create Issues due to 'Could not load validator' class Errors:

    Cause

    Some JIRA instances rely on 3rd party workflow validator tools to set conditions, validators or post-functions on an issue during it's lifecycle at some issue operation or transition within a workflow. JIRA will lazily load any 3rd party classes required at the first time of use. If the class is not present, the issue creation may fail.

    Diagnosis

    • Browse to the appropriate project administration screen.
    • From there, browse to the workflow in use.
    • Find the transition that's throwing the error.
    • Note the particular validator. The validator will specify a code that suggests which plugin you need. Check the resolution for the known plugins that cause this issue.

    Resolution

    Download the applicable Jar from the vendor. A clue of the plugin responsible is often yielded from the stack trace; check for the name of the vendor. The set of known plugins to cause this issue include:

    • JIRA Suite Utilities
    • JIRA Misc Utilities
    • Minyaa Suite

    Be sure to use the correct version, and also to remove any previous version of that plugin.

    Once installed, restart JIRA.
