@ChuYanLon, could you copy/paste the full stack trace? You can get it using the command :messages. Thanks

[alexandre-abrioux]

@ChuYanLon and if you can, also paste the full content of ~/.config/nvim/lua/config/coding/blink.lua, that may help. Thanks

[alexandre-abrioux]

@ChuYanLon could you also provide your blink.cmp version? Could it be related to this fixed bug? Saghen/blink.cmp#446

[ChuYanLon]

There is still a problem with configuring auto_sthow_delay_ms=500

[alexandre-abrioux]

@ChuYanLon If you edit the following list

default = { "lazydev", "lsp", "path", "snippets", "buffer", "emoji", "npm" },

and change the order of your sources so that npm is not the last one, for instance, like so:

default = { "lazydev", "lsp", "npm", "path", "snippets", "buffer", "emoji" },

; then do you still have blink-cmp-npm in the stacktrace?

[alexandre-abrioux]

@ChuYanLon Thanks. The stacktrace still shows blink-cmp-npm, so it's not related to source order.

In the video, I see that the error happens after you type :. Does it happen if you don't type :?

[ChuYanLon]

No input will result in no error

[alexandre-abrioux]

@ChuYanLon I've opened an issue Saghen/blink.cmp#1957 and a potential fix Saghen/blink.cmp#1958 in the blink.cmp repository.
