we can see only first type '(' trigger completion, second letter 'p' not trigger:

Have you the same problem with vscode?

[angelozerr]

I have tried with TypeScript Language Server and it is working.

no, vscode work well

[CppCXY]

I think it might be that I returned an empty array when '(' was triggered, and then lsp4ij continued with this empty completion item instead of retriggering.

Please share LSP traces of vscode and lsp4ij to compare them.

Please share LSP traces of vscode and lsp4ij to compare them.

I remember explaining before that VSCode does not have a dedicated trace configuration; it requires support from the plugin itself. Therefore, I can only share the logs recorded by my language server.

It does. Try to add in your settings.json

"lua.trace.server": "verbose" and you should see lua in the Ouput of the terminal.

I suggest that your vscode extension declare this settings in the package.json like we did in https://github.com/redhat-developer/vscode-xml/blob/37571ca1c310ffc27f97992bccce6035f383aa99/package.json#L213
