Problem handling arrays/lists

[justjoheinz]

Please start the example using:

clackup -s apispec -s ningle ningle/app.lisp

Query the user "database", e.g. with httpie:

http :5000/users

Expected result: an empty array response, like [].
Actual result: NIL is invalid for #<ARRAY {700A657303}>

Query the db for a non-existing user:

http :5000/users/0

Response is correct. User is not found.

Add a user:

http POST :5000/users name=SomeUser

Empty response seems to be correct

Retrieve this user:

http :5000/users/1

Expected result: the json representation of the user SomeUser.
Actual result: #<APISPEC/EXAMPLES/NINGLE/APP::USER {700A1ACF23}> is invalid for #<OBJECT {700B009DA3}>:
Not an association list

Retrieve all users:

http :5000/users

Expected result: json array of all users
Actual result:
(#<APISPEC/EXAMPLES/NINGLE/APP::USER {700A1ACF23}>) is invalid for #<ARRAY {700B009D83}>:
Not an array
