Google Ads API sporadic errors

Hi,

I'm seeing different errors thrown sporadically when making calls to the click conversions upload API 

Firstly - io.grpc.StatusRuntimeException: UNAUTHENTICATED: Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.

Most calls are successful with our API credentials but sometimes it returns this error randomly it seems, do new credentials need to be generated or is there an issue with current ones?

I'm generating the client object using the properties file.

Secondly - I'm seeing Google Ads exceptions thrown with no messages and just request ids, here are examples of some
