When making a WebService call from workflow using a correct XML the below error is see in UI. The error does not happen all the times but sometimes. The webservice is called inside a loop from a workflowIGL version 702 P07

Error in Workflow UI - Error History:

<?xml version="1.0" encoding="UTF-8"?><createChangeRequest><Request type="fulfillment"/></createChangeRequest>

The XML sent is:

<Changes><Notes>Bulk Account Processing</Notes><AccountChange><Operation>Create</Operation><User>112233</User><BusinessSource>NA.ABC.COM</BusinessSource><Parameters><Parameter><Name>ACC_TYPE</Name><Value>CreateGeneric</Value></Parameter><Parameter><Name>ACCOUNT_NAME</Name><Value>sbthrgen</Value></Parameter><Parameter><Name>STR1</Name><Value>OU=Users,OU=ABC,OU=AM,DC=na,DC=abc,DC=com</Value></Parameter><Parameter><Name>STR2</Name><Value>CN=Domain Users,CN=Users,DC=na,DC=abc,DC=com</Value></Parameter><Parameter><Name>NUM1</Name><Value></Value></Parameter><Parameter><Name>NUM2</Name><Value></Value></Parameter></Parameters></AccountChange></Changes>

Below is the error seen in log:

If you take the exact XML and try to send a request using a 3rd party tool, is the change request created successfully or you are getting the same error?

Thank you. I tried the exact same xml and token using an external client and was successful. Please note that this web service call is in a loop and the first 2 iterations are successful on the third item it has this issue - on going to actions resetting any of previous nodes - the webservice call is successful with the exact same parameters - not sure if looping has any issue with webservice calls? We have another workflow to reset password by creating CR in a loop and that works fine.

It’s the create account with the issue.

Also this is what I see:

HttpStatusCode:	409
HttpStatusMsg:	Conflict

StatusCode:

RSA004 : Request Failed

If I have a loop for 5 account creation - it failed with above error for 3 and created just 2 CR for account creation

I would try to add a delay node for 20 seconds in the loop and see if it solves the problem

I have tried that approach as well a few days back - delay was for 3 min - still failed in 3rd iteration. The first two were success. I can try once again. Am trying to understand from you why we need delay if token is different and data is different on each iteration?

It looks like it’s failing on the account name creation, is the account template and naming policy you use generating unique account names?

Yes it is, as already mentioned there is no data issue - works fine. It’s with the looping and making web service calls

Can you enable debugging here so we can maybe understand what is going on here?  From the error message it sure seems like we are hitting some form of a race condition where multiple requests might be settling on the same account name after pluggin in all the parameters for the account template.

Please try enabling the following log4j categories:

com.aveksa.server.core.cr.ChangeRequestServiceProvider
com.aveksa.server.command.CreateChangeRequestCommand
