Googlebot receiving missing template error for an existing template

Question

In the last couple of days, we have started to receive a missing template error when the google bot attempts to access our main home page (welcome/index). I have been staring at

Answer 1

the interesting part in the error that you posted is :formats=>["*/*;q=0.9"]

the rails-app tries to find a template for the format "*/*;q=0.9" which is not going to work.

i guess that google is somehow using this as a format query parameter like welcome?format=*/*;q=0.9

afaik latest rails versions will just render a 406 in those cases.
