    I got a fixed AS3 Version 3.57.0-12 that fixes this issue in my tests.

Same kind of issue here, no declaration can be pushed on 17.5.1.6 with AS3 v.3.56. Rolled back to 17.5.1.4, everything works fine again.

The kind of error we have in lab:

{
 		"code": 400,
 		"declarationId": "autogen_-------",
 		"host": "localhost",
 		"message": "failure querying config for tenant Common (POST http://svc_account:XXXXXX@localhost:8100/mgmt/tm/util/bash execute bash command response=403 body={\"code\":403,\"message\":\"Direct access to /mgmt/tm/util/ is not permitted.\",\"restOperationId\":19551208,\"kind\":\":resterrorresponse\"})",
 		"tenant": "Common"
 	}
