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

[barry91-acn]

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.

I just find an relevant info for the issue about SAP CDS sub.modules

Imports from @sap/cds/apis/... are no longer supported!
As a consequence of the above, always only import @sap/cds APIs, while imports from @sap/cds/apis/... were always wrong and don't work any longer with cds8:
import { Service } from '@sap/cds'
import { Service } from '@sap/cds/apis/services' // WRONG!
As already rolled out in December 23, imports references to undocumented .d.ts files, as in line 2 above, was never documented, hence always wrong. While we still supported them for a grace period since then, this grace period ends with cds8.

So this first error disappeared after adjustments indicated here: https://cap.cloud.sap/docs/releases/jun24
