>>Uncaught TypeError: Cannot read property '0' of null<< while uploading image on production

[Averethel]

When I'm trying to upload image on staging server I keep getting Uncaught TypeError: Cannot read property '0' of null javascript error.
On development everything works just fine so that's quite weird. I checked that no request have been made so it's even weirder.

I use rails 4.0 and ruby 2.0.

Same here.

Same here. Any ideas how to resolve this?

imagemagick was not installed in my case...

[Averethel]

Yeah, same for us.

[pascalbetz]

No, not even sure the project where we used the lib is still active.

As we wrote - the problem was imagemagick was not installed on the machine.
