Error messages shown: SearchPanes : "No data available in table"
Description of problem:

Hello,

My problem is related with this thread.
I am also trying to implement SearchPanes with server side DataTables, using Python Flask but there is nothing related to SearchPanes in POST request to server:

I also tried to pass searchPanes.options from server, nothing is changed.

So I created MVP with this issue, there are two versions: with "serverSide:" false/true (I'll close it when the problem will be resolved).
Source code is available at Gist
To run it: put HTML files in "templates" folder, run "pip install -r requirements.txt", and "python3 app.py" then.

SearchPanes doesn't actually send any information to the server when nothing is selected - see this example.

What is needed is for the server to respond with a searchPanes object with the options to display (see docs here), which your Python script is currently not doing.

I'm afraid we don't write in Python ourselves - none of our published libraries are in that language, so I can't really help you with that aspect.

Thank you a lot
It was not clear from the manual that first you need to send a searchPanes object from the server with the data you want to display on the page in searchPanes.

I updated Gist, now it works how it's supposed to do (maybe not so efficient in terms of database access).
