Should this be address in phoenix? It seems like phoenix should protect itself from another dependency pulling in an incompatible version of cowboy (2.8.0).
This would save us from having to explicitly declare the correct cowboy version in our mix.exs file. When we really don’t care about what version of cowboy we are using.
I ran into the same issue when running a mix deps.update new_relic_agent resulted in new_relic_agent 1.18.0 => 1.18.4 which caused my cowboy to be updated from 2.6.3 to 2.8.0, cowboy 2.8.0 is pulling in cowlib 2.9.1 which is the actual root of the issue, because cowlib 2.9.1 will not compile with phoenix.
Or is this a cowboy issue that 2.8.0 should have been a major bump?
Also, I would argue that the correct fix for this, at least in my situation would be to add
{:cowlib, "~> 2.8.0"}
to deps in your mix.exs file. This is the bare minimum requirement
