GCP Compute Engine API Filter Issue with startTime and endTime in Java

Question

I'm working with the Google Cloud Platform (GCP) Compute Engine API in Java and encountering an issue when trying to filter operations based on startTime and endTime within a specified time range. The code snippet I'm using is as follows:

Compute compute = (Compute) GcpServiceClientUtility.getGoogleCloudServiceClient(GcpService.COMPUTE, credentialDetails);
assert compute != null;

// Fetch operations within the specified time range for a specific project
String filter = String.format("startTime eq %s",
        "2023-11-28T03:36:48.839-08:00");
OperationList operationList = compute.globalOperations().list(GcpConfigService.getKeyValueFromFile(credentialDetails, PROJECT_ID)).setFilter(filter).execute();
for (Operation operation : operationList.getItems()) {
    log.info(operation.getName() + ": " + operation.getTargetLink() + " " + operation.getOperationType());
}

However, I'm encountering the following error:

Invalid value for field 'filter': 'startTime ge \"2023-11-28T03:36:48Z\"'. Invalid list filter expression.

It seems that the issue arises when trying to filter operations based on a time range using the startTime field. I've tried using the ge (greater than or equal) operator to specify a range but without success.

How can I properly filter operations in GCP Compute Engine API using startTime and endTime within a specific time range?
