Dialogflow-fulfillment-nodejs: Dialogflow Not Compatible with Azure Functions

[AskYous]

I can't get Dialogflow to read my response from my webhook. It keeps reading Chinese letters. I deployed a Webhook Fulfillment to Azure Functions. However, when Dialogflow tries to use it, it just responds with:

Webhook call failed. Error: Failed to parse webhook JSON response: Expect message object but got: "笀ഀ਀  ∀昀甀氀昀椀氀氀洀攀渀琀吀攀砀琀∀㨀 ∀嬀吀攀猀琀崀 䠀攀氀氀漀 昀爀漀洀 夀漀甀猀攀昀⸀∀Ⰰഀ਀  ∀漀甀琀瀀甀琀䌀漀渀琀攀砀琀猀∀㨀 嬀崀ഀ਀紀".

I'm currently emailing dialog flow support, and they mentioned that it could be a legitimate bug... that Dialog flow is not compatible with Azure Functions.

Hi, Even I'm getting the same error, any workaround for this?

[AskYous]

Unfortunately no. They wanted to work with me to debug this but I didn't have anymore time to do so (and I'm not working with DialogFlow at the moment).

Is there any progress on this matter? @AskYous have you found a workaround?

[AskYous]

No progress unfortunately.

Work around for me was to switch to AWS

[SimonHaasnoot]

Found out a way that works on Azure Functions with C#. Couldn't get it working with NodeJs unfortunately.

In case you guys still want a solution, i found one which is working :)

Perfectly explains the situation.
