I fairly new to this but was sure I made the same connection last week with no issue. I am not sure what I am doing wrong. I am trying to create a connection to a dataset in a SharePoint site. To do this:
1. Select Connect to Data
2. Navigate to my dataset in the SharePoint files connections (to note, sometimes I cannot find the site on the SharePoint list to make the connection which is odd in of itself)
3. Select Next
4. If the data is small I can get it to pull up but I need to connect to datasets that are millions of lines it will give me this error. I have tried just walking away for awhile to do its thing, but it still won't load.
To note, I have no power over the format. It has to be excel. I cannot just connect to the original source's database. Because of the nature of the transactions it also has to be a huge amount of data. My end goal for this is to not have to connect to the data each time the flow is needed to be run let it be run on a schedule.
