I can't make it work on AWS rails app

[belarba]

On my machine it works fine (using gem 'wkhtmltopdf-binary-edge', '0.12.6.0').
But I'm not able to make it works on my AWs server.

On AWS I changed the gem to gem 'wkhtmltopdf-binary'
I updated the wicked_pdf initializer to use the use_xvfb: true

But I get this error:

RuntimeError (Failed to execute:

["/usr/bin/xvfb-run", "/usr/local/bundle/bin/wkhtmltopdf", "--encoding", "utf8", "--orientation", "Landscape", "file:////tmp/wicked_pdf20200903-1020-1ul2zdw.html", "/tmp/wicked_pdf_generated_file20200903-1020-sjwtr2.pdf"] | ["/usr/bin/xvfb-run",

Error: PDF could not be generated!

Command Error: ):

Any clues?
