Hi,

The invalid ELF header error usually occurs when you commit your node_modules folder that was created on a different OS.

It’s not recommended to commit node_modules into your repo, so that the package manager (npm, yarn, etc.) can determine the correct packages for the platform when installing.

Does that mean you need to delete node_modules folder from git repository?

I did the same as you recommended but this time i receiving a different error …

You’ll need to check the filepaths are correct and nott hat Render use Linux with a case-senstive filesystem.

Ensure your code references to file are exactly as they are shown in GitHub. For example, you seem to have various casing in the logs you shared:

/Api/index.js

So maybe models and/or category are actually Models and/or Category?
