Datasources - CSV Upload Error

Uploading 38 MB CSV file gives this error
Cannot find anywhere in the documentation, however, STAgile allows for 50 MB upload. Please clarify.

Hi, They are tools based on different technologies, try removing unnecessary columns or uploading the CSV to the database.

What is the max size that can be uploaded? I have run into this issue as well. I was trying to upload a 50mb .csv file to test out this system.
