CAP CDS Node.js cannot query to Hana Cloud

[former_member664605]

Hi,

I have CAP CDS Nodejs service and was running properly so far. Suddenly started giving the below exception, whenever I invoke OData API. Does anyone has encountered similar issue?

Hi Sreekanth,

What changed? For example, was there a deployment with new node modules? Something must have caused this.

Best,
