Getting null result on datatable

Trying to get results from a workday instance but getting null at runtime. Tried with “Connection Window” at config button, and it gets results after a while, but not when running thewhole process.

It seems activity doesn’t wait enough time to finish getting report so it gets a datatable with null.

At the end, what we are trying to achieve is to save reports on a SQL Server DB.

Any ideas of how can I get workday reports without this kind of issues?

Getting repots by using configuration tool, so no authentication issues:
