Errors TS2307 and TS2322 (langchain, sap/cds and LLMType)

Unfortunately I'm facing the following issues. I already updated langchain and sap-cloud-sdk libraries.

• npm i -g sap-cloud-sdk
• npm install @sap-cloud-sdk/openapi
• pip install -U generative-ai-hub-sdk[langchain]

Do you face the same?

Just for your info: I already builded successfully without any issue a version of this repository of June/July. This is why I think something is changed around library. But honestly now I do not understand what's needed to update/change in order to complete the build.
