[BUG] Callback Error: binary.lua:82: Expected value but found unexpected end of string at character 8127

[jsco2t]

Describe the bug
The following error is generated when using /explain-code (in chat-ui):

Error executing vim.schedule lua callback: ...share/nvim/lazy/tabnine-nvim/lua/tabnine/chat/binary.lua:82: Expected value but found unexpected end of string at character 8127
stack traceback:

        vim/_editor.lua: in function <vim/_editor.lua:0>

Steps to reproduce the behavior:

1. Open Golang project
2. Use :TabnineChat to open chat UI
3. Use slash command: /explain-code
4. Select text as requested by chat-ui and ask the chat-ui to continue

hi @jsco2t can you please provide the go project + what lines exactly are you selecting? is it consistent? for every selection?

hi. I'm hitting the same issue. here's the code and error I see in nvim after applying the patch from #94. note that I've redacted most of the fileUri path in the error output but replaced it with the same number of chars. here's what I did:

1. open main.go
2. use TabnineChatto open chat ui
3. select the entire main function (lines 3 - 54)
4. use slack command /explain-code
5. the answer is generated in the chat ui and I see the error in nvim.

fwiw, I've also seen similar behavior if instead of /explain-code, I ask it: refactor the selected code to append an increasing integer to the ‘Hello, World!’ message (the incomplete json content in the error is obviously a little different).

I'm using:

# nvim --version
NVIM v0.9.5
Build type: Release
LuaJIT 2.1.1710088188

# sw_vers
ProductName:            macOS
ProductVersion:         14.4
BuildVersion:           23E214

# grep tabnine ~/.config/nvim/lazy-lock.json
  "tabnine-nvim": { "branch": "master", "commit": "f0eb52aaf4992c838b40a3f825459ed5080a128a" },

[edited after]
I forgot to mention, if I remove the patch in #94, I see this:

Error executing vim.schedule lua callback: ...share/nvim/lazy/tabnine-nvim/lua/tabnine/chat/binary.lua:82: Expected value but found unexpected end of string at character
 8193
stack traceback:
        [C]: in function 'decode'
        ...share/nvim/lazy/tabnine-nvim/lua/tabnine/chat/binary.lua:82: in function ''
        vim/_editor.lua: in function <vim/_editor.lua:0>

note the char number diff: 8193 in mine vs. 8127 in the bug title/original error message. char 8193 does correspond to the json cutoff in my gist.

I'm unable to reproduce this, but I believe I know what the issue is.. give me couple of days to solve this

Hi guys, can you test this #168 ?
Appreciate your feedback since i'm not able to test it (does not reproduce to me)

[thbishop-intuit]

Hi @amirbilu. I tested the patch in #168 with my example and it works successfully. I also tested a much larger version of the same function (> 10,000 lines) and it worked successfully as well. Thanks so much for the quick response/patch! 🎉

[amirbilu]

Highly appreciated the detailed issue! Merging it now
