KenesisVideoFrameTransportCallback Error 4102

[chorhatarahuduketuri]

I'm taking part in an AWS-run community time trial race at work. I am only using the DeepRacer console, no custom SageMaker or ros anything.

I'm getting this error, and I have no idea why - is it related to trying to watch the video while the training is going on?

All my models are now returning this about 10 minutes into training.
