Geocoding api return 400 error 'FilterBBox' must have more southwesterly position before more northeasterly position.

Hi I'm getting a 400 bad request error with POST /places/v0/indexes/<indexname>/search/suggestions with the following request playload:

{
"Text":"Auckland","MaxResults":10,
 "FilterCountries":null,
 "FilterBBox":[166.2890625,-47.4578085307503,-169.096590380423,-34.1105560631211]
}

I initially tried [166.2890625,-47.4578085307503,190.903409619577,-34.1105560631211] and that returned another error 'FilterBBox[2]' must be between -180 and 180. Thus I had convert 190.903409619577 to -169.096590380423.

Please advise.
