W3001 Data Mapper Error

I am getting the following error

12:05:40.339 [0010] W3001 : Error while executing plugin: HTTP/1.1 500 An unspecified error occurred which was caused by LoggedApplicationException: There was an error running the data mapping process caused by ApplicationException: Error executing DM configuration: The step is out of bound (DME000130) (DM1000031) (SRV000012) (SRV000001)

I had this issue previously and it was suggested that I use the “Validate All Records” button to locate the problematic records which was a great solution.

Currently I have come across the issue again, but when I used the “Validate All Records” button I do not have any problematic records, but the process still cannot execute the data mapper.

Any suggestions?

The error you get is provide by Workflow (actually the connect Server through Workflow (actually actually the Datamapper engine through the Connect server through Workflow :wink: )).
“Validate All Records” button is inside the Connect Designer.

It could be that the data you have in your Designer at the design time is different than the one process through Workflow.

I suggest that in Workflow, you first run a Datamapper with the output type “None (validate only)”.

You can then use that to check if the data is ok before you process it for real. Based on the result you can also , when errors come out, copy the incoming data file and test it in the Designer to figure out the issue.
