I am trying to parse a fixed-width format file, but I am getting an error when I try to enter values in the "column offsets" field. It allows me to save my settings without error, but it never generates a preview or schema. When I go back to the "Explore" tab, it gives the following error: "Failed to run". Followed by: "For input string: "2"". The number there is always the first value I put in the "column offsets" field.
I tried to included screenshots here, but the image embed button is not working for me (won't let me upload a file).
