I’m new to Phoenix and Elixir. I recently got involved in a Phoenix api project which was build ages ago. It has the following versions:
- Phoenix 1.3.0.
- Elixir 1.5.1
I follow the instructions provided by the previous developer and tried to run the project. However I can’t install the older version of Elixir and Erlang to test the api. It left me to upgrade the phoenix project to 1.6.15. I followed @chrismccord guide and also followed [phoenixdiff](https://phoenixdiff.org/?source=1.3.0&source_variant=default&target=1.6.15&target_variant=default) and successfully migrated and ran the server.
Upon running the server, I ran into so many problems. If I tried to access the any endpoints, I run into 500 Internal Server Error. Not sure what is exactly going on and unable to figure It out how to debug the code and so. Sorry for being a newbie.
Any help on what maybe wrong and why am I getting the Error code: 500? Any helping hands?
