Dataflow Error - Index was out of range. Must be non-negative and less than the size of the collection

[Syndicate_Admin]

Hi,

I have setup Dataflow to sync data from one CRM online instance to another CRM online instance using odata feed data source.

I am syncing one Table record and mapped couple of fields. I have mapped Integer, String and boolean fields. 

Dataflow is failing with below error - 

"Index was out of range. Must be non-negative and less than the size of the collection"

Can you please help.

Hi,

Issue is resolved now.

There was one custom plugin registered on pre-operation which was throwing this exception.

Thanks,

Bipin

Hi @binpinshan,

In the following post, he encountered the same issue, and he solved the issue by reinstalling Power Query:
