Frequently Asked Questions
Why does the ChatSDKError have no HTTP status code?
When an error returns without an HTTP status code, it typically means the failure occurred locally within the SDK before a formal network request could be completed or processed by the WhatsApp server.
Can standard Microsoft 365 support fix Omnichannel SDK issues?
Generally, no. The Microsoft 365 and SharePoint communities focus on standard productivity apps. Omnichannel is part of the Dynamics 365 ecosystem, which requires specialized support from the Dynamics community.
What causes the MessagingClientConversationJoinFailure error?
This error is usually caused by incorrect SDK initialization parameters, missing authentication tokens, or network configuration blocks that prevent the client from successfully joining the WhatsApp conversation stream.
