The error wtforms.validators.ValidationError: The CSRF session token is missing in pgAdmin 4 within Docker typically occurs when there is an issue with the CSRF (Cross-Site Request Forgery) token, which is used for security purposes to prevent unauthorized requests.

To resolve this error, you can try the following steps:

  1. Clear your browser cache: Sometimes, the issue is related to stale or invalid CSRF tokens stored in the browser cache. Clearing the cache and refreshing the pgAdmin 4 page can help resolve the problem.

  2. Check the Docker environment variables: Ensure that you have correctly configured the necessary environment variables for pgAdmin 4 in your Docker environment. Specifically, make sure that the PGADMIN_ENABLE_CSRF environment variable is set to True. This is required to enable CSRF protection.

  3. Restart the Docker container: Try restarting the pgAdmin 4 Docker container. This can help refresh the application state and resolve any temporary issues.

    • Stop the running container using the command: docker stop <container_name_or_id>
    • Start the container again using the command: docker start <container_name_or_id>

  4. Verify the Docker network settings: Ensure that the Docker container hosting pgAdmin 4 is correctly connected to the network, and the necessary ports are properly exposed. Ensure that you are accessing the correct network address and port in your browser.

  5. Update to the latest pgAdmin 4 version: If you are using an older version of pgAdmin 4, consider updating to the latest version. Newer versions often include bug fixes and improvements that can resolve issues like this.

If the issue persists after trying the above steps, it's possible that there may be an underlying problem or a specific configuration issue with your Docker environment. You can check the pgAdmin 4 Docker image documentation or seek help from the pgAdmin community or support channels for further assistance.
