Hi Avinash,
Did you just upgrade to 7.8 and are using a widget which isn't ready(or updated) for 7.8 yet?

Hi Avinash,
So csv export template is using the deprecated function "getSudoContext()"
More infor here, go to tab deprecated functions: https://apidocs.mendix.com/6/runtime/com/mendix/systemwideinterfaces/core/IContext.html
Also mentioned here, so yes, deprecated for all versions of 7:
https://docs.mendix.com/refguide/moving-from-6-to-7
You could try to see if an update in the app store is available or replace the function yourself with the new function "createSudoClone()".
