Viz swallows full traceback, making debugging difficult

Description

As per title

Context

I'm not able to open the Viz view of my project, and the information provided in the logs is not enough to understand what's happening.

In my particular case, I have this

2025-05-08 14:27:04.341 [info] [Error - 14:27:04] Kedro-Viz: "Unable to find credentials 'pinecone': check your data catalog and credentials configuration. See https://kedro.readthedocs.io/en/stable/kedro.io.DataCatalog.html for an example."

But my Kedro environment is properly configured, and kedro run works without problems. So I have no way to know where the problem is.

Steps to Reproduce
