数据未通过mqtt从nodered传输到Thingsboard

Question

I try to send data to thingsboard via mqtt. The mqtt node shows connected status but data is not transferring to thingsboard. Eventhough data is in json format, data is not receving in thingsboard. Any help will be more helpful.

sample sending data:

{    "main-door": "closed",    "main-light": "OFF"}
