Microsoft.Bot.Schema.ErrorResponseException: Operation returned an invalid status code 'BadRequest'

Question

Thanks for taking a look at my questions.

The exception of the application exactly as the title.

It was deployed at the AWS server and was integrating with Skype.

The Microsoft.Bot.Schema.ErrorResponseException did not happen when I'm testing my application on local with bot emulator.

It happens only when on Skype.

Env:

• Microsoft.Bot.Builder 4.2.2
• Microsoft.Bot.Builder.AI.Luis 4.2.2
• Microsoft.Bot.Builder.AI.QnA 4.2.2
• Microsoft.Bot.Connector 4.2.2

Microsoft.Bot.Schema.ErrorResponseException: Operation returned an invalid status code 'BadRequest'

--- End of stack trace from previous location where exception was thrown ---

Did anyone know possible reasons of this bug?

Again, thank you so much for helping me.

Answer 1

Because in the message that I sent, it contains HTML tags. So that may crash the application.
