Creating Azure Discovery schedule fails with error "Required attribute datacenter_type is missing for CI Type cmdb_ci_cloud_service_account".Issue Trying to create a new Azure Discovery schedule fails with error "Required attribute datacenter_type is missing for CI Type cmdb_ci_cloud_service_account". Understanding is there are 8 mandatory fields on cmdb_ci_cloud_service_account table. Out of which account_id, datacenter_type are defined on the same table and are mandatory per OOB. All others are coming from parent table which is where these are marked mandatory, the "Azure Create Service Account" pattern is responsible to scan the credentials and locate all the required attributes for creating the Discovery schedule. Debugging the pattern "Azure Create Service Account", step "Get Subscriptions" executes the API "https://management." + $resource_url + "/subscriptions?api-version=2020-01-01" and which is being failed with below error Test failed: Custom operation Cloud REST - add response to context failed to execute script due to Custom operation Failed to run script due to the following error: JAVASCRIPT_CODE_FAILURE: Can't find method org.apache.http.impl.client.HttpClientBuilder.setMaxConnPerRoute(null). (script_include:CloudHttpClientBuilder; line 40). Check the discovery logs for more details. The above error might lead the investigations to think if the configured credentials for Azure having issues, but, it may not be always the credential issue. If executing "Discover Datacenters" from the Service Account directly, the discovery complete successfully, which mean the Credentials are good.
