Expo + React Native + Self Hosted OTA not working

I am trying to host OTA on my own server. I followed the Hosting Updates on Your Servers guide but with no luck.

To dig deeper I called the method Updates.checkForUpdateAsync() and logged the error message.

Error Code: ERR_UPDATES_CHECK
Error Message: Failed to parse manifest data

However, I checked the manifest URL and got the JSON response.

What am I missing? Thanks in advance.
