Expected & Actual behavior (期望与实际表现)

Source of Issue: C:\Users\Khwaish.vscode\incubator-hugegraph-ai\hugegraph-python-client\src\pyhugegraph\utils\huge_config.py
Problematic Code:
line 66:

except Exception as e:  # pylint: disable=broad-exception-caught
                traceback.print_exception(e)
                self.gs_supported = False
                log.warning(
                    "Failed to retrieve API version information from the server, reverting to default v1."
                )

Expected Behavior: Upon clicking "Extract Graph Data", the output should be generated for the RAG index builder.

Actual Behavior: Error thrown and unable to perform "Extract Graph Data". Displays errors on both the console and the UI.
Error: Traceback (most recent call last):
File "C:\Users\Khwaish.vscode\incubator-hugegraph-ai.venv\lib\site-packages\pyhugegraph\utils\huge_config.py", line 68, in post_init
traceback.print_exception(e)
TypeError: print_exception() missing 2 required positional arguments: 'value' and 'tb'

Cause of error discovered:
The traceback.print_exception function requires two more positional arguments, value and tb, which are not provided in the calls from KG Builder.
i.e:

builder = KgBuilder(LLMs().get_chat_llm(), Embeddings().get_embedding(), get_hg_client())
File "C:\Users\Khwaish\.vscode\incubator-hugegraph-ai\hugegraph-llm\src\hugegraph_llm\utils\hugegraph_utils.py", line 39, in get_hg_client
return PyHugeClient(
File "C:\Users\Khwaish\.vscode\incubator-hugegraph-ai\.venv\lib\site-packages\pyhugegraph\client.py", line 59, in __init__
self.cfg = HGraphConfig(ip, port, user, pwd, graph, graphspace, timeout or (0.5, 15.0))
File "<string>", line 11, in __init__
File "C:\Users\Khwaish\.vscode\incubator-hugegraph-ai\.venv\lib\site-packages\pyhugegraph\utils\huge_config.py", line 66, in __post_init__
traceback.print_exception(e)

Solution discovered:

builder = KgBuilder(LLMs().get_chat_llm(), Embeddings().get_embedding(), get_hg_client())
File "C:\Users\Khwaish\.vscode\incubator-hugegraph-ai\hugegraph-llm\src\hugegraph_llm\utils\hugegraph_utils.py", line 39, in get_hg_client
return PyHugeClient(
File "C:\Users\Khwaish\.vscode\incubator-hugegraph-ai\.venv\lib\site-packages\pyhugegraph\client.py", line 59, in __init__
self.cfg = HGraphConfig(ip, port, user, pwd, graph, graphspace, timeout or (0.5, 15.0))
File "<string>", line 11, in __init__
File "C:\Users\Khwaish\.vscode\incubator-hugegraph-ai\.venv\lib\site-packages\pyhugegraph\utils\huge_config.py", line 66, in __post_init__
exc_type, exc_value, tb = sys.exc_info()
traceback.print_exception(exc_type, exc_value, tb)

Actual Behavior:
During the try block, throws exception in the console, then proceeds to complete functions.

Hey @Kryst4lDem0ni4s! I'm here to help you out with any bugs, questions, or contributions you have in mind. Let's tackle this together!

The error you're encountering is due to incorrect usage of the traceback.print_exception function. This function requires three arguments: exc_type, exc_value, and tb, which represent the exception type, value, and traceback, respectively.

To fix the issue, you should modify the code in huge_config.py to correctly pass these arguments. Here's how you can do it:

Replace the problematic code:

except Exception as e:  # pylint: disable=broad-exception-caught
    traceback.print_exception(e)
    self.gs_supported = False
    log.warning(
        "Failed to retrieve API version information from the server, reverting to default v1."
    )

With the corrected version:

except Exception as e:  # pylint: disable=broad-exception-caught
    exc_type, exc_value, tb = sys.exc_info()
    traceback.print_exception(exc_type, exc_value, tb)
    self.gs_supported = False
    log.warning(
        "Failed to retrieve API version information from the server, reverting to default v1."
    )

This change ensures that the traceback.print_exception function receives the correct arguments, allowing it to properly print the exception details.
