Upload pic broken (on live osdemo)

[balat]

Uploading a pic on http://ocsigen.org/ocsigen-start/demo/settings
fails. Nothing happens when submitting the picture.
Error message in browser console:

Eliom_client_value.Exception_on_server("(Failure int_of_string)")

I will try to reproduce the issue locally, and we will see.

I uploaded a picture with success on a local computer but on google cloud server I got the same issue.

It seems to be related to Os_uploader.record_image because I replace
"Os_uploader.record_image avatar_dir ~ratio:1. ~cropping photo"
by
"Os_uploader.record_image avatar_dir photo"
in the file projectname_handlers.eliom and it works.
