That argument takes a local path.  You would need to copy it up to s3 after its complete.

Hi everyone,
We’re having some problems about saving fax files to s3 when getting faxes with rxfx.
All is well when we give a local path for file but when it comes to give s3 url it doesnt work at all.
Is that even possible? 
Best regards.
