Hi , 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 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. ---

Hello Aleazan, Can you run a GET request on your Event Hook endpoint and take a screenshot of the response you get and post it here? Make sure that your output is encoded in UTF8 as well: [Event hook verification failed - Could not deserialize response](https://devforum.okta.com/t/event-hook-verification-failed-could-not-deserialize-response/7736) ---
