How can i add page_id and access_token without hardcoding in module-1

I tried different formats of requests but unit testing is failed

by using private variables of class as mentioned in TODO there are clear instructions for how to use access_token and Page ID. Revisit it!

should i add self.page_id and self.page_access_token in

Very close to the solution. search it how can you apply this and you can also read In module 1 I am not getting what to do after giving image url and name for more help

still not able to do it

Did you tried sending requests via Postman?
Are you using the correct URL, check the slacks #announcement channel message at 5:07 PM.
Check the parameters needed in Postman and find a way to do the same in workspace via code.
Find a correct way to pass parameters. Google and stack overflow it.
