[BUG] APINames are not extracted

### Release version

v6.0.1.4

### Describe the bug

The API is displayed in the log (trace) but is not written to a file. Everything else is extracted correctly.

Strangely, it works with the following configuration, but i don't need extractAll.

JSON is displayed there.

### Expected behavior

Extract API with apiNames: value

### Actual behavior

Extract api with apiNames value not possible

### Reproduction Steps

```
workspaceNames:
- ignore

apiNames:
- myAPIName

backendNames:

#- ignore

productNames:
#- ignore

subscriptionNames:
- mySubscriptionName

tagNames:
#- ignore

policyFragmentNames:
#- ignore

versionSetNames:
#- ignore
