Hi Oscar,

Are you getting this error in the front-end console or is it in an HTTP client?
If this is in your react app, it seems like something is wrong with the proxy config.

It was showing this error inside Chrome Devtools (where localhost:3000).

Are you able to insert data through an HTTP client like Insomnia or postman?

I think I found the issue. I had included the sentence "proxy": "localhost:5000" inside the package.json belonging to the server, and not inside the package.json of the client(react app). May be that one the problem Thiago? Because now I´m not getting any errors.

That was it, for sure Oscar.

Let me know if you have any other questions! :)
