I have the same issue loading a CSV. If you ignore the error the collection will run and complete the selected number of iterations however it uses the first line in the CSV for all the iterations. As a result I've not been able to test the new feature for 0 iterations using all the lines in the file; #1342. Selecting 0 just runs a single iteration using the data from the first line.

I've mailed my collection, data, environment and run result to help@getpostman.com.

EDIT: My normal installation prompted me to upgrade which I did. I've now uninstalled Postman (Windows x64) and reinstalled the Canary channel. I now get the Data File Type and Preview controls which were not present before. The file format error is only shown when clicking Preview but the issues running the collection persits.

Testing using 0 for the iterations appears to run a single iteration. Afterwards the recent run list shows a running collection (in blue) and the details have no requests and the progress % is NaN. You can't Stop Run so you have to delete the recent run.

I'm unsure if this is related or just not a feature but inspecting the run results none of the Request information has been populated with the data used in the iteration.

@karinamkl @davecanderson We've released a fix for this, and you should be able to use your CSV files properly now. Can you update your app to the latest version (4.9.1) and verify if the fix works for you?

@numaanashraf Updated for version 4.9.1 and I'm able to attach/preview JSON and CSV files and run collection with them successfully. Also able to see array of objects from JSON in preview.
