LspDocumentDiagnostics runs before file is fully saved

[jhod0]

To automatically show diagnostics when I save a file, I added the following to my .vimrc:

autocmd BufWritePost * LspDocumentDiagnostics

However, using pyls, if I add something like the following to a file, and then write with :w:

dummy_string = 'Hello there!'

I get the diagnostic message EOL while scanning string literal. When I write again a second later, it gives the correct diagnostics. It seems like lsp is using diagnostics from a partially-updated file?

I may just be using vim-lsp wrong, in which case a suggestion how to do this properly would be appreciated. Thanks!

My work around for this issue:

function! FormatAndWrite()
LspDocumentFormatSync
:w
endfunction
autocmd BufWritePost * silent! call FormatAndWrite()
