Errors with VectorCode + Copilot - Claude Sonnet 4

[ruslanfialkovskii]

I'm not sure if this is a problem in VectorCode or in CodeCompanion, but it is definitely related to the Copilot provider and the Claude Sonnet 4 model. I always get an empty error when trying to use VectorCode with Copilot - Claude Sonnet 4. With other models, I don't have such trouble.
Errors messages:
[vectorcode.nvim] [ERROR 16:17:06] /Users/ruslan/.local/share/nvim/lazy/VectorCode/lua/vectorcode/integrations/codecompanion/query_tool.lua:586: CodeCompanion tool with command {

[vectorcode.nvim] } thrown with the following error: { "" } <---- why empty ???

So, should I open a bug report in CodeCompanion spaces or in VectorCode?
Used the freshest versions VectorCode and CodeCompanion.

Does querying from the CLI work? Try something like vectorcode query introduction, and see if it throws an error. The query messages are indeed not ideal. Sorry about that.

[ruslanfialkovskii]

Actually, it is not failing; it shows an error message and proceeds, but errors occur almost on every request.

Ok I'll take a look at that. Sorry for the delayed reply. I'll probably need to start from improving the logging, so that we can get more info out of these errors. I'll figure something out over the weekend.

I've made some changes to the cmd backend that calls the CLI command in #285 . This will hopefully improve the error propagation route. Please give it a try and see if the error message tells us more about your issue. I tried it with copilot sonnet 3.7 and have no problems.

I have tried 'fix/cmd_jobrunner_error_propagation' branch, but got the same result—the same empty error in the Claude Sonnet 3.7 and 4 versions model. With GPT-5, this problem does not exist.

Although I haven't been able to fix it yet, something seems to be wrong when I try to use the --exclude flag in the CLI. It gives empty results and doesn't throw error messages. I was also able to reproduce in codecompanion. There have been some changes to the underlying data structures in order to support alternative database backends, and I might have broken things. I'll try to figure it out. Maybe fixed by #287 (requires installing VectorCode CLI from source)?
