Index was out of range

[jidl-gh]

Hello, when I run the tool for certain folder I get and 'Index was out of range error':

Starting the log-in window
Log-in successfully, retrieving the reports...
Starting conversion and uploading the reports 03/09/2020 06:58:56
Found 21 reports to convert
Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Any ideas what this refers to?

I'm getting the same error when attempting to run the CI_1791266 version - and it's not allowing the script to run successfully.

I too have the same error, also the CI_1791266 version.

Also still an issue with the pre-release version CI_2110572

this might look like a bug in the tool, but I believe its just confusing error reporting:
When I debugged code I saw that there was a swallowed exception caused by one of our reports having an unsupported drill down feature: "Drillthrough feature is not supported. Paginated reports with drillthrough cannot be uploaded."
If you can't debug this tool, same error may be seen on Power BI web UI when trying to manually import converted .rdl file.
Hope this helps someone.
