I have fixed this issue by removing layout: false from render_errors in config.ex

Thank you all for your support.

Hmm, as a sanity check – the stacktrace suggests that you are migrating to v1.7 and not v1.5, is that what you set out to do?

And since it’s working fine in your dev environment but not QA environment after adding the phoenix_view dependency, have you double checked that the CI/CD pipelines run mix deps.get for your QA environment?

If the code says 1.7.2 in the stacktrace, then you are running 1.7.2. Try calling mix deps and confirming which version Phoenix is running on.

Add {:phoenix_view, "~> 2.0"} to your mix.exs. Is a required step when migrating to Phoenix v1.7.
