(node:40) UnhandledPromiseRejectionWarning: TypeError: Cannot set property 'filename' of undefined about opendatacam

This sounds like an error in your config.json. Without seeing the file I cannot be more specific than telling you to check how you configured the video input. See also https://opendata.cam/docs/configuration/#video-input

Thanks for the response.
I am using the default config.json and no changes. I see the file demo.mp4 file in there.

After multiple tries now it shows its loading the default demo.mp4 but then I am hitting the issue mentioned here #614

http://localhost:8070 is showing the following so no inference

 "objects": [ 
  {"class_id":0, "name":"person", "relative_coordinates":{"center_x":0.968587, "center_y":0.155538, "width":0.142953, "height":1.267735}, "confidence":0.865290},

 ] 
}, 

Keep in mind, I am using default config.json and no changes.

Somewhere something is pointing to the wrong config file or the settings in config.json is not getting loaded/assigned.
