This error is occurring because the required 'async-redis' module is missing or improperly installed in your project. When your application tries to load the 'async-redis' module from the 'node_modules' directory, it fails because it cannot locate the necessary files. This could be due to several reasons, such as an incomplete or failed installation, a version mismatch, or a misconfigured package.json file that does not list 'async-redis' as a dependency.
To resolve this issue, first make sure you have the 'async-redis' package listed in your package.json file under "dependencies." If it's missing, add it with the appropriate version number. Next, run
npm install in your project root directory. This command will install all the dependencies listed in your package.json file, including 'async-redis'. Ensure there are no errors during the installation process. If you still encounter the error, try deleting the 'node_modules' folder and reinstalling your dependencies by running
npm install again. Lastly, if you suspect a version mismatch, check the 'async-redis' npm page for the latest version and update your package.json file accordingly, then repeat the installation process.
