I am at https://github.com/neoclide/coc.nvim/commit/64b63ed1e6c6517ce45b136eb4b0ef0f4ba1b10f and still can reproduce this.
I cannot trigger completion (auto trigger or even press ctrl-space) when I'm inside a function call.
Completion works fine when I'm not inside a function call.

I also tested using coc-go with go.trace.server set to verbose. When inside a function call, I trigger the completion manually by pressing ctrl-space, I can see the completion candidates returned by gopls in :CocInfo, but there is no completion popup.

No idea, checkout https://github.com/neoclide/coc.nvim/wiki/Debug-coc.nvim

I just did a git bisect and saw that the bug is caused by af2b7f5 as mentioned ealier by @voldikss.

I also tested ceb9e47 (the commit that closed this issue) but it didn't fix the bug for me.

I'm not familiar with typescript and coc.nvim codebase so I don't think I can help debug this issue.

Can you take a look at af2b7f5 again @chemzqm ?

[chemzqm]

I can't reproduce, please use latest release branch of coc.nvim.

[mnrce]

Sorry, I tried again with all coc extensions disabled except for coc-tsserver, and the issue goes away.
Look like the culprit is coc-postfix, there was something in ceb9e47 that caused it to break. Can you take a look at it @fannheyward?

[fannheyward]

@mnrce just released coc-postfix 0.0.8 with a quick fix for this issue, please give it a test. If you still have any error, please open an issue at https://github.com/fannheyward/coc-postfix/issues
