My docker container is invalid

Hello, I encountered an issue last night while trying to upload my Docker container. After building it, I attempted to upload it, but I received an error stating that my container is invalid. I'm uncertain about the criteria for a valid container. Could you please provide some guidance on how to resolve this issue? Any assistance would be greatly appreciated.
