Hello everyone, I am working on a large dataset with 1.8M rows and 150 columns, until a few days ago everything was working fine then I did some transformation and now when I load the query in Powerbi I get this error:
OLE DB or ODBC error: [DataSource.Error] Received an unexpected EOF or 0 bytes from the transport st..
I am quite new to this world and I can't seem to solve this, I have isolated some steps that seem to be creating problems.
(When individually changing/deleting each step the query loads correctly in Pwbi)
My Issue is that I do not see any problem in those problematic columns, at least not from power query, all values are rendered correctly and there are no weird situations at first glance therefore I do not know where to fix what. The only thing that I have noticed is that it takes a lot of time to load all the query in powerbi (20 min at least) and maybe there is a different way to organized the data.
You can find all the files here: https://we.tl/t-pEJ3Z4qqFg
The problematic steps are under the query "LOP" and are called:
Thanks to everyone for the help! Any input will be highly appreciated.

One cause for the OLE DB or ODBC error on refresh can be the data privacy settings being mismatched for different data sources.
Try checking the privacy level for each data source or changing the setting for the current file to ignore privacy levels and see whether that helps.
Unfortunately, this did not solve the issue.
