Hi I git clone the master branch and do yarn to install node modules.
When I do yarn dev I have the following error:

The console output:

Do you have any thoughts on what could be wrong?
Thanks!

Did you try hard coding the URL to your API instead of using PublicRuntimeConfig etc. Because your API_URL should be in .env file, and that file is not in the git repo. You need to create it yourself.
