Event hook verification failed - Could not deserialize response

I am testing out the event hook feature in Okta, but when I try to verify the endpoint, the message came out to be:

Unable to verify event hook. Could not deserialize response due to error at Line 1 Column 1

My Azure functions will detect the X-Okta-Verification-Challenge header and outputs a response something like: { “verification”: “ks58ZrThPLf22kTDavKLhm9aukKNECTmg–3gpsw” }

What am I doing wrong here?
The authentication field, secret and header fields are empty in the settings.
Thanks.

Dear All,

Problem is solved.
The output needs to be encoded in UTF8.

Hi kwoonfai…

We’re getting this same error while trying to setup an Event hook that calls a Snaplogic API…

In azure…how did you format the output for UTF-8?
