Hey @mariushosting, I'm here to help you with any bugs, questions, or contributions. Let's work together to solve the issue you're facing.

To resolve the error "An error has occurred while fetching types" with the latest Docker image of logspace/langflow, consider the following steps:

  1. API Endpoint: Ensure the getAll() function in ../controllers/API is correctly configured to reach the intended API endpoint. Verify the endpoint URL and network connectivity.

  2. Error Handling: Check the console output for more details on the error message to understand the root cause.

  3. Network Issues: Confirm there are no network issues preventing the Docker container from accessing the API.

  4. API Response: Ensure the API is returning the expected data format. The functions typesGenerator, templatesGenerator, and extractFieldsFromComponents depend on the structure of the data returned.

  5. Loading State: Verify that the loading state is correctly managed using useFlowsManagerStore and useAlertStore to avoid premature termination of the fetch process.

  6. Docker Configuration: Verify that the Docker image is correctly configured and up-to-date. Rebuild the image if necessary.

If these steps do not resolve the issue, further investigation into the specific error message logged in the console is needed [1].

You’ll need to pull from the docker hub first, I would guess you have a previous image with that tag locally.

Then try the command docker run -p 7860:7860 langflowai/langflow:latest.
