DidChange API is not working

[prajith936]

Hi,

I am usin g CCLS server with python LSP client. I have a few files modified in my codebase after the initialize step of LSP client. After modification of the file, I am querying for document symbols using "documentSymbol" API and I am getting the error: "-32600, 'not indexed', None". I tried using 'didchange' API of the LSP client even then i am getting the above error.

What is the approach to be done for the above case?

Thanks
