Hello,
some api's returns when a problem occurred are blur
For example, the api instrument
https://api.fusionfabric.cloud/investment-management/reporting/v1/reports/Instruments
whitout body (yes, it's stupid for a POST request, but it's an example)
Another example is the exchange rates api if a currency unknow is post (for exemple baseCurrency=EUR2 )
Response : constraint violation
some api return "oops, Something is wrong !"
this type of response does not explain the problem...
