This issue may or may not be related to Adding data table to page disables graph interactivity
When I added a datatable to a separate tab in my Dash app, it worked fine for a while. I was able to build the basics and then apply some styling. Then, all of a sudden, it stopped working, giving me Error loading layout instead. If I disable the tab with datatable, everything works again.
The browser shows 500 INTERNAL SERVER ERROR
GET request is as follows:
scheme: http
host 127.0.0.1:8050
filename /_dash-layout
Then goes
Status: 500 INTERNAL SERVER ERROR
Version: HTTP/1.0
Transferred: 19.47 KB (19.26 KB size)
Referrer Policy: no-referrer-when-downgrade
At the bottom of the console I see
Response is missing header: content-type: application/json
which is true: in the response headers section there’s only
Content-Type: text/html; charset=utf-8
Please, advise. How can I fix this?
UPD: This is NOT a local issue: when I deployed the app to Heroku, I got exactly the same behaviour.
