Common Errors
ModuleNotFoundError6 reportsThe "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.
FetchError2 reportsThe "FetchError" in Vercel Functions usually indicates a problem resolving the URL or network connectivity when making an external fetch request. Ensure the URL you are fetching from is publicly accessible and correctly formatted (including `https://`), and that your Vercel function has outbound network access enabled if required (especially when connecting to private resources).
