Azure Monitor Java SDK -MismatchedInputException: Missing required creator property 'timespan'

Question

I'm using the Azure Monitor Metrics SDK in my Java application to query metrics for redis resource. However, I'm encountering a com.fasterxml.jackson.databind.exc.MismatchedInputException with the error message "Missing required creator property 'timespan' (index 0)". How could I fix this?

This is my code snippet:

			<dependency>
				<groupId>com.azure.resourcemanager</groupId>
				<artifactId>azure-resourcemanager-redis</artifactId>
				<version>2.39.0</version>
			</dependency>
			<dependency>
				<groupId>com.azure</groupId>
				<artifactId>azure-identity</artifactId>
				<version>1.12.1</version>
			</dependency>
			<dependency>
				<groupId>com.azure</groupId>
				<artifactId>azure-monitor-query</artifactId>
				<version>1.3.2</version>
			</dependency>

final MetricsQueryClient metricsQueryClient = new MetricsQueryClientBuilder() .credential(clientSecretCredential) .buildClient()
final MetricsQueryResult metricsQueryResult = metricsQueryClient.queryResource(instanceId,Arrays.asList("usedmemory"));

The full stacktrace is :

After adding these permissions to my azure app, this problem gone:
