Flow with custom connector for D365 Business Central fails to decode special characters in http response

Hello everyone,


I am trying to get a custom connector working for Dynamics 365 Business Central on iOS. It works flawlessly on Windows but it fails on iOS:  "Error parsing HTTP message header byte 28 of message System.Byte[]".


The response is fine :

    "error": {
        "code": "Application_DialogException",
        "message": "Eingabe ueberprüefen.  CorrelationId:  b723f390-fa08-4dde-ae38-c15c2938edad."
I believe it can not decode any of the following characters: 'ä, ö, ü'. D365 BC itself uses the characters on some errors, so I need a workaround/fix for this. 
My flow:

Has the error occured to anyone too?

Hi @COcak ,


At first I thought it could be related with the issue below:


However it looks to be a completely different issue, are you able to run the application to Android as well? The issue is only with iOS?

Hello @danielbazetto ,


I am able to run the application on Android as well, but the issue is still there on Android.  
Once the response contain any of the following letter : "ä, ü, ö" , it will display a http decode error with the byte of the character (see first post). The problem must be related to the core where it parses the http response.


I apologize, I must correct myself: It does not work on any platform.
