Image Analysis - Error code may be missing when Input image is too large

Hi,

When I call Image Analysis (v4.0, via C# SDK) with 20MB+ image, I receive this error (see that there is no InvalidImageSize error code:

The image size is not allowed to be zero or larger than 20971520 bytes. Status: 400 (Bad Request) ErrorCode: InvalidRequest
 
Content: {"error":{"code":"InvalidRequest","message":"The image size is not allowed to be zero or larger than 20971520 bytes."}}

Is the error code intentionally missing? I would expect the same behavior as in other error cases - eg. when the image has wrong dimensions, I receive this error with a specified error code:

The image dimension is not allowed to be smaller than 50 and larger than 16000. Status: 400 (Bad Request) ErrorCode: InvalidRequest
 
Content: {"error":{"code":"InvalidRequest","message":"The image dimension is not allowed to be smaller than 50 and larger than 16000.","innererror":{"code":"InvalidImageSize","message":"The image dimension is not allowed to be smaller than 50 and larger than 16000."}}}

Are the Image Analysis error codes for version 4.0 the same as for version 3.2?
