Error Message : InvalidKey: A key should contain at least a kind

Question

I am getting following error while trying to update the entity in google cloud datastore:

InvalidKey: A key should contain at least a kind.
    at keyToKeyProto (/Volumes/Drive B/dev/zapi/node_modules/@google-cloud/datastore/src/entity.js:696:11)

I don't know why is this coming for.

Thanks in advance.

When you trying to access key and key is not available when no data available, it gives the error

"Error Message : InvalidKey: A key should contain at least a kind"

To avoid this error first make sure that [datastrore.KEY] is available.
