Subject: [PATCH] fix(provider-meta): guard body.to in sendMessageToApi for
 typing indicator

sendMessageToApi always called fixPrefixMetaNumber(body.to) which throws
TypeError when body.to is undefined (as in the typing_indicator payload).
This caused the typing indicator to silently fail with an empty error.
