Troubleshooting

Troubleshooting

Solutions to common issues and errors you might encounter when using Koderupa.

Authentication Issues

Error: "Invalid API key"

This error occurs when your API key is invalid or has been revoked.

Solution:

  • Check that you've correctly set the API key in your environment variables
  • Verify that the API key is valid in the Koderupa dashboard
  • Generate a new API key if necessary
Error: "Email already in use"

This error occurs when trying to create a new user with an email that's already registered.

Solution:

  • Implement a check to see if the email is already registered before attempting to create a new user
  • Provide a "Forgot Password" option for users who may have forgotten they already have an account
  • Consider implementing social login options to reduce the need for multiple accounts

Database Issues

Error: "Permission denied"

This error occurs when a user tries to access or modify data they don't have permission to.

Solution:

  • Check your security rules to ensure they're correctly configured
  • Verify that the user is authenticated before attempting to access protected data
  • Implement proper role-based access control for your application
Error: "Document not found"

This error occurs when trying to access a document that doesn't exist in the database.

Solution:

  • Check that you're using the correct document ID
  • Implement error handling to gracefully handle missing documents
  • Consider using transactions for operations that depend on multiple documents
// Example of proper error handling
const getDocument = async (id) => {
  try {
    const doc = await db.collection('items').doc(id).get();
    
    if (!doc.exists) {
      console.log('Document not found');
      return null;
    }
    
    return { id: doc.id, ...doc.data() };
  } catch (error) {
    console.error('Error getting document:', error);
    throw error;
  }
};

Deployment Issues

Error: "Build failed"

This error occurs when the build process fails during deployment.

Solution:

  • Check the build logs for specific error messages
  • Ensure all dependencies are correctly installed
  • Verify that your code passes all linting and type checking
  • Test the build process locally before deploying
