Invalid character in message

[junaidk]

if there are some invalid characters in request body, a page with stack trace opens like at this url and and It is impossible to go back to Bin view to view other requests.

Opening bin url displays a blank page.

Error: Invalid character (�) in string: { \"ssid\": \"value\", \"message\" : \"msg\", \"time\" : \"9999\" }�[D�[D at index 67

@junaidk seems like an encoding problem.

can you please paste the body you're using here?

[junaidk]

this is the message body { \"ssid\": \"value\", \"message\" : \"msg\", \"time\" : \"9999\" }^[[D^[[D . It has left arraow key chars at the end.
It starts show error page after receiving this message. And there is no way to go back to Bin.

related to encoding by xmlbuilder in https://github.com/Mashape/mockbin/blob/master/src/middleware/negotiate-content.js#L49

My use case was emojis, althought it was valid json it would throw on this line. According to the module author it can be allowed by adding the {allowSurrogateChars: true} flag to the call. In my case i was handling the instagram api which is sprinkled with emojis and other special characters.

I tested with the string above and it now doesn't throw invalid and renders fine.
