Multilanguage RAG - completly puzzled

[mxsteini]

Hi together,
for days I have been trying to somehow build a multilingual RAG system.
I am now completely annoyed. After watching 10h tutorials, I thought this can't be hard ...
Here is my workflow.

The “Conversational Agent” reports “Received tool input did not match expected schema”

The other “Tool Agent” does not respond at all. In Langfuse I see that it is somehow unhappy about the json in the tools.
