Issue/Introduction

When run cf-mgmt CLI to update space quotas for TAS foundation, it might fail with error as shown below.

$ ~/cf-mgmt update-space-quotas  --config-dir=config --user-id=cf-mgmt --client-secret='changeme' --system-domain=my.sys.example.com

Property log_rate_limit_in_bytes_per_second is available in /v3/space_quotas API endpoint since version 3.125.0. And cf-mgmt CLI starts to support property log_rate_limit_in_bytes_per_second since version 1.0.68. For TAS this property is supported in 3.0 and later releases. 

In this case the cf-mgmt CLI version is 1.0.69 and TAS version is 2.11.47. Therefore cf-mgmt update-space-quotas command would submit a CAPI call to TAS including property log_rate_limit_in_bytes_per_second which can't be recongized by target TAS yet, which caused the error. 

Environment

Product Version: 2.11

Resolution

There are two ways to address the issue:
1. Use one cf-mgmt CLI version earlier than 1.0.68
2. Or upgrade TAS to 3.0+ if cf-mgmt CLI version is 1.0.68 and later
