ATF test error 'TypeError: Cannot read properties of undefined (reading 'toString')' was detected

[RenataN]

Hi everyone,

I am running ATF tests, and one of them is showing the following error message: "TypeError: Cannot read properties of undefined (reading 'toString')' was detected on the page being tested."

It appears during the step to open an `sc_task`. I analyzed the table configurations but didn't find any code using "toString()" that references an undefined variable.

Could someone please help me resolve this issue?

Thanks.
