Typically, this error is solved by re-running the Alteryx workflow. It looks like you have tried that and it hasn't worked. Can you paste a screenshot after running your workflow?
I recreated your example in the two screenshots. The Before Execution screenshot is directly after opening the yxmd file, and I get the "no valid metadata" error. After running the workflow, the error goes away, and I can see the output data in the "After Execution" screenshot. Note that this warning comes back when you click off of the Python tool. The data is passed to Jupyter via a cache, allowing you to interactively modify the data in your notebook. You will need to re-run the workflow to send the updated data to your downstream tools.
I made a few changes to my Notebook and designer layout to reflect what you have. I've attached the file with the complete notebook. I also have a complete log. Are you seeing in yours that the data was successfully written to anchor #1?
If you try to create a new workflow with the default horizontal layout and white background, do you get the same error? What if you Browse for a csv instead of text input?
