The sequence doesnt have any trouble, it runs perfectly. But to do so i have to select the forst instance and run from that activity with my right click, instead of simply debuging the file and running it as a whole.
Object reference not set to an instance of an object.

tried moving to a new xaml but i got the same error.
If i used classic wl activities in a w version can that be causing the error? It doesnt make sense to me since it actually runs fine when i give it a right click and run from the first activity, its only a debug problem.
This error means you are referencing a variable or argument that has not been initialized. Show us your code and which activity is generating the error.
Please dont copy your out sequence…instead copy all other activities or each activiry and then check running…it is clear that there is some issue with your outer sequence
I did various fixes… beginning from moving the rpa to a new xaml following @Anil_G advince and then rechecking each argument to see he advice of @jack.chan . It did the trick, it ran from debug with no problem.
So as expected we moved the rpa to our server to do background tests… same error of “object reference not set to an instance of an object”, with more errors in the details:
Object reference not set to an instance of an object.

i think there is a version difference. From 23.6 to 21.4. But they both are over 21.4 which according to the packs i use should give trouble after that version.
