Fix ModuleNotFoundError

in Vercel Functions

Solution

The "ModuleNotFoundError" in Vercel Functions typically arises when the required Python dependencies declared in your `requirements.txt` file haven't been installed before deployment. To fix this, ensure you have a `requirements.txt` file in the root directory of your function's code containing all necessary packages, and verify that Vercel is correctly installing these dependencies during the build process by reviewing the deployment logs for any installation errors.
