I posted an update to googleapis/google-http-java-client#367 which would remove the need for this hack entirely.

We can fix this but we need a release of google-http-java-client first.
elharo commentedon Oct 31, 2019
http-java-client released, proceeding

How to fix this? I am using below dependency for datastore
org.springframework.cloud:spring-cloud-gcp-starter-data-datastore:1.1.2.RELEASEelharo commentedon Jun 10, 2020
Make sure you're using the latest version of the datastore and http clients. libraries-bom 5.6.0 should give you this.
