Kennethware-2.0: Deployment testing errors

We do have  ID and  Developer Key, and   when adding Kennethware 2.0 to canvas course use   suggested XML-> all code is obtained form github

Anyone know why $url will be  malformed?

Note>>In Warning test posted here , I replaced “client_id”  and “code” with XXXX  just for this posting, in fact they are
existing data, ID is what canvas assign and CODE -> seem to be encrypted

Is it  a Developer Key that  is failed to be  properly  encrypted/decrypted and that is why  I’m getting the error? Or something else?

Any ideas how to get around that?

Thanks for your question  @tatiana_peisl ​. I'm cc'ing  @kenneth_larsen ​ and  @travis_thurston ​ who may be able to answer your questions more directly.

Hi  @tatiana_peisl ​,

It would appear that you entered the word "secret" on line 28 of your config.php file instead of the client secret that was supplied to you by Canvas along with your client ID. Both the client ID and the client secret that you received from Canvas are required in order to request an OAuth token.

Let me know if that still doesn't fix it.
