Solution:<\/h3>\n
From the message, we see that we use the "main<\/strong>" function as a handler, which has no incoming arguments.<\/p>\n
\r\ndef main():\r\n<\/pre>\n
 <\/p>\n
And to run, you need a handler of 2 arguments "event<\/strong>" and "context<\/strong>", so you need to bring the function declaration to the following form:<\/p>\n
\r\ndef main(event, context):\r\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
