[BUG] [VSCode Extension] JSONDecodeError: Expecting value: line 1 column 1 (char 0)

[valentincve]

I am having an issue with Visual Studio Code: I cannot execute my script. None of my queries work, and they fail, saying that a value is incorrect.
It seems like no request is being executed or able to connect to the server.

The module causing the issue is: "Index lookup".

I use Python 3.10.15 (/isr/local/bin/python)
"promptflow": "1.16.1",
"promptflow-azure": "1.16.1",
"promptflow-core": "1.16.1",
"promptflow-devkit": "1.16.1",
"promptflow-tracing": "1.16.1"

Everything works perfectly (Python scripts, queries, etc.) on the web.
However, it is slow, so I want to switch to Visual Studio Code.
I have therefore used this feature:

My flow.dag.yaml file is exactly the same between the Web and Visual Studio Code; there is no issue with code differences.

But when I use this feature, after installing all dependencies and prerequisites, I encounter an error with all my queries:

When working from the web, everything functions properly, and I can see traffic in the usage of the index in question. However, via Visual Studio Code, there’s nothing, no traffic at all, even though the authentication is correct.

Here is the error:JSONDecodeError: Expecting value: line 1 column 1 (char 0)

If you use a tool from promptflow_vectordb. There has been a bug for several weeks inside a tracing method.

See: #3837

You need to add an environment variable BUILD_INFO with a string like '{"build_number" : 0}' in the same session where you launch your flow.

If you want to use the UI to run your code.
Try to add the env in a terminal and launch vscode with the command code (path to your project).
