azure app-service returning ERR_CONTENT_DECODING_FAILED

Question

I have deployed my node application to azure but getting on all sides this error message: ERR_CONTENT_DECODING_FAILED

I have already tried several things like putting this into my web.config

<urlCompression doStaticCompression="true" doDynamicCompression="true" />
    <httpCompression>
      <dynamicTypes>
        <clear />
        <add enabled="true" mimeType="text/*"/>
        <add enabled="true" mimeType="message/*"/>
        <add enabled="true" mimeType="application/x-javascript"/>
        <add enabled="true" mimeType="application/javascript"/>
        <add enabled="true" mimeType="application/json"/>
        <add enabled="false" mimeType="*/*"/>
        <add enabled="true" mimeType="application/atom+xml"/>
        <add enabled="true" mimeType="application/atom+xml;charset=utf-8"/>
      </dynamicTypes>
      <staticTypes>
        <clear />
        <add enabled="true" mimeType="text/*"/>
        <add enabled="true" mimeType="message/*"/>
        <add enabled="true" mimeType="application/javascript"/>
        <add enabled="true" mimeType="application/atom+xml"/>
        <add enabled="true" mimeType="application/xaml+xml"/>
        <add enabled="true" mimeType="application/json"/>
        <add enabled="false" mimeType="*/*"/>
      </staticTypes>
    </httpCompression>

But nothing works. Can someone help?

The website I deploy is this one: https://github.com/aumanjoa/chronas-community

I took your website and deployed to Azure App Service. After setting the CLOUDINARY_URL value in App settings and connection string of mongo, I got the error as below.

Here is my web.config for reference.

Obviously, the error differs from yours. So, you may confirm whether your application runs fine locally before you deploy it to Azure. Also, note that gzip compression is enabled by default without any operation. You can check out Azure Web App Not Using GZip Compression and gzip compression in Windows Azure Websites for details.
