How do I resolve the “TypeError: str.match is not a function” error in a React application?

When developing applications with Syncfusion React components, you might encounter the error message “TypeError: str.match is not a function.” This error can be frustrating, but it’s typically related to package management within your application. This article will guide you through the steps to effectively resolve this error.

Reason for the error

The error “TypeError: str.match is not a function” is commonly triggered by issues with package duplication or incompatibility. This can happen when multiple versions of the @syncfusion/ej2-base package are installed in your application.

Solution for the error

To fix this error, you should ensure that your package environment is clean and that all dependencies are compatible. Here are the steps to follow:

1. Check package.json file:
   Review your package.json file to verify that you are not explicitly including any component-dependent packages. It’s best practice to let these packages be installed automatically to maintain compatibility with the versions of the main component packages.

2. Remove package-lock.json:
   Delete the package-lock.json file from your application. This will allow a fresh installation of the packages without any cached versions interfering.

3. Delete Syncfusion folder in node_modules:
   Go to the node_modules directory and remove the @syncfusion folder. This step ensures that any conflicting or duplicated packages are eliminated.

4. Re-install packages:
   Execute npm install or yarn install to reinstall the necessary packages with the corrected configurations.

By following these steps, you should be able to resolve the “TypeError: str.match is not a function” error in your React application.
