Troubleshooting

Mix cannot locate Erlang or Elixir#

Inspect both the selected Elixir SDK and its internal Erlang SDK. Run elixir --version and mix --version in the intended environment and compare with the IDE. Restart a run configuration after changing SDKs.

A debugger breakpoint is skipped#

Confirm that the code executes in the selected run configuration and that its module is not excluded from interpretation. Recompile after changing source, and check that the process uses this project’s build output.

Credo or Dialyzer results are missing#

Confirm dependencies and provider settings, then run the tool through the project’s normal Mix environment. Fix provider startup or dependency errors before investigating editor highlighting.

Report an issue#

Use email support and include:

• Your IDE edition and full build number from Help → About.
• The installed plugin version; this manual covers 2026.1.15.
• Relevant external-tool versions, the failing action, and a small reproducible example.
• The error message and relevant log excerpt, with credentials and private project data removed.

Use Help → Show Log in Finder/Explorer to locate IDE logs when requested. Describe what you expected to happen and whether the same operation works from a terminal.
