How to get to the step throwing error in PowerBI Dataflow

[smjzahid]

I have a dataflow with (60 transformations steps) applied to it, and pulling in data from 50 different tables with various data sources like (Sharepoint, Dataverse, csv files) etc. However, the scheduleed refresh is failing with below shown error. 

Is there a way to find out exactly at which step (within the dataflow) the error crops up, which then failes entire data refresh.

As this is very difficult to go through individual tables and files to find out the reason for this error

@smjzahid , Check for change datatype step, this error is with some logical datatype column

You have one in middle, but there can be more than one.
