Hi there,
When I try to add a signature to the petition, I get the following error ({"result":"failure","messages":["authorization key cannot be found or is not granted"]}1).
But if I perform an Auth Key request, I get the following ({"result":"failure","messages":["source has already been taken"]}1).
I also tried performing and Auth Key request with another source value and received a result:success and status:granted response. But if I again try to add a signature, I get the cannot be found or is not granted message.
I'm sure I'm missing something obvious.
Thanks!
