Regression : File fields export results in DB error

It was possible to export fields earlier as the file field was exported as the link

But now it gives DB error as it looks like it is trying to put in content instead.

Database Error Code: Data too long for column 'custom_13' at row 1, 1406

I was able to replicate this on dmaster as well
