Literal carriage return. Run script through tr -d '\r'

Question

I'm executing a simple Bash Script and I got this warning on Visual Studio Code.

Literal carriage return. Run script through tr -d '\r'

I'm not sure if I must install an extension to solve it or it's a syntax error.

The code I'm using is:

#!/bin/bash
echo "Hello"

I tried installing an extension in Visual Studio Code. I expect the warning to disappear.
