Hi!
This trace back points to a wrong component configuration in:
self.config[_c] is expecting an object where it can call model_dump(), but it’s finding only a string.
I have just reproduced the following steps in order to do a clean install of Verba:
# WARNING! this remove all previous content that was stored in Weaviate Embedded
rm -rf ~/.local/share/weaviate/*
mkdir verba-run
cd verba-run
python -m venv .venv
source .venv/bin/activate
pip install goldenverba
verba start
Make sure you doesn’t have any environment variable configured that may be interfering.
Here you find possible env vars:
Let me know if this helps.
