I am trying to access my page from a different domain and need to turn off CORS, however when i try this suggested solution i get the error in the title.
EDIT: I see now it was entirely removed from dash.py - it would be useful if this was added to the obsolete list so a more informative error comes up in future, given it appears in so many previous solutions
For future reference, we recommend looking at the package’s CHANGELOG.md file when you upgrade: dash/CHANGELOG.md at 000d7758ab46cd0e4ab6ee07dbe3c5967d27bffd · plotly/dash · GitHub
Fair enough, although I did not upgrade, i was already using the latest version but looking at (not so old) solutions which referenced that keyword.
I have a related question: I still have the underlying problem. I am trying to embed the dash app as a div using ngrok as a test bed and so get
No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
as the browser error.
Is there a way to access the underlying Flask app to fix this? I have tried a variety of suggestions with flask-cors and so on but nothing seems to work. I think it would work if i can access the specific response headers given in a layout back to the browswer, is that possible?
EDIT: problem solved, extracted the server via CORS(app.server)
What was the CORS config that you used? I am running into this same issue. Thanks!
