I recently got into this error on my raspberry pi running (rasbian) a phoenix app… I guess there is some kind of version missmatch but I cannot figure it out. Maybe someone knows whats wrong?
It crashes with the following error on every http request:
[error] 3914- fatal: :expected_element_start_tag
[error] Failure while translating Erlang's logger event

maybe “compiled with Erlang/OTP 21” and running on “Erlang/OTP 22” is the problem?
