Troubleshooting

Docker Issues

1. Verify Docker is installed and running:

docker --version
docker ps

2. Check Docker permissions:
   • Ensure your user has permissions to run Docker commands
   • On Linux, add your user to the docker group: sudo usermod -aG docker $USER

Reports Directory Issues

1. Verify the reports directory:

   • The directory specified in MAIGRET_REPORTS_DIR must exist
   • Your user must have write permissions to this directory
   • Check permissions: ls -la /path/to/reports/directory

2. Common configuration mistakes:

   • Missing MAIGRET_REPORTS_DIR environment variable
   • Directory doesn't exist
   • Incorrect permissions
   • Trailing slashes in the path

3. After fixing any issues:

   • Save the configuration file
   • Restart Claude Desktop
