API Gateway with swagger documentation export error

Question

I added one piece of documentation on our api gateway using the web UI and when I try to export it as swagger, I get the following error:

>  Cannot deserialize value of type `java.lang.String` from Object value (token `JsonToken.START_OBJECT`) at [Source: UNKNOWN; line: -1, column: -1] (through reference chain: io.swagger.models.ModelImpl["default"])

Here is what the documentation part looks like:

What am I doing wrong?

The documentation is expecting a 'String' type value and you're offering an 'Object' type value.

Change either like this:

```
"{'Documentation': 'Global Authentication'}"
```

or

```
"Documentation: Global Authentication"
```

The way I resolved the error was to delete the stage and then add it back, then the error went away.
