Have you updated also he OQL Module from the market place?
Check also for diplicate jar files in the userlib.
Hi Rajinkumar,
I can see that this problem ocurred with the Marketplace module Simple CSV Exporter. I'm noticing that the latest release is for Mendix 9, so that may be the issue, the Marketplace component has not been updated since 2022 and it's probably not compatible with Mendix 10:
I recommend switching to another module or creating your own logic to replace this module in case the module is not going to be updated.
I hope that can help you solve your problem, best regards!
