squakez opened a new pull request #5177:
URL: https://github.com/apache/camel/pull/5177
Checking that the value to be converted from a String to List is an array in
order to avoid a BsonInvalidOperationException when the method is called.
With this PR we fix a minor issue caused when we try to convert to a List,
ie:
```
if (exchange.getIn().getBody(List.class) != null) {
List<?> body = exchange.getIn().getBody(List.class);
...
```
The above call would fail with a single document as the method assumes it's
going to be an array of them. We should therefore return `null` if the passed
in value is not an array and not proceed to the conversion.
