IntelliJ doesn't show all diagnositics and codeAction doesn't work

[linghuiluo]

As shown in this screenshot, the diagnostics in class CryptoUtils are not listed in the LSP Inspection Results. Actually there should be 9 errors, but IntelliJ just shows 4 and the diagnostic messages are all followed with "No longer valid".

The results are totally non-deterministic, sometimes InteilliJ doesn't show LSP inspection results at all and sometimes it shows all expected results when I rerun "Inspect code".
How does the LSP-plugin deal with diagonsitics in IntelliJ?

The language server i wrote will perform analysis whenever a file is performed didOpen or didSave. It works perfectly in eclipse and vscode.

I also built quick fix in my language server via code action, it is shown with lightbulb icon, however, when I click the quick fix button, nothing happens....(see screenshot below)

Can anyone help me by this issue? I would really like to have my server work in IntelliJ.

Thank you very much!
