Getting error "Can not capture site screenshot" on linux, AWS

[facultymatt]

We're attempting to get Manet running on Amazon Web Services (AWS). We have successfully got things running but we are not getting an image.

Here are some details:

• Manet is displaying "Can not capture site screenshot".
• No image is being generated.
• We have isolated this issue to SlimerJS returning exit code 255.
• We had the same issue when deploying to a linux environment in house.

Any ideas?

To update, we fixed this issue by installing Firefox browser.

Turns out this is a requirement - although its not that clear from any documentation here, or on SlimerJS website.

To get it running on AWS, this helped: https://gist.github.com/hmkly/42210b28be6a0bdaa24d
