TypeError: Object of type 'bytes' is not JSON serializable

Question

I just started programming Python. I want to use scrapy to create a bot，and it showed TypeError: Object of type \'bytes\' is not JSON serializable when I run the project. <

Answer 1

Not all datatypes can be json serialized . I guess pickle module will serve your purpose.
