Plugin fails to parse 'parameter_names' #39

Open indiejames opened 1 month ago

indiejames commented 1 month ago

When I try to load collections from my endpoint with the plugin I get the following error:

Populating data query attributes failed due to the following error: list indices must be integers or slices, not str

My EDR endpoint is simply returning the example collections output from the OGC docs here https://app.swaggerhub.com/apis/OGC/ogcapi-edr-1-example-1/1.1.0#/Capabilities/listCollections

The output is reproduced here:

I have tried a simpler JSON response, but the result is the same. It happens when I add parameter_names to the response.

It appears the the tools are struggling with the schema and the auto generated example has errors in the definition of arrays in the extent and parameters sections.

bbox and interval attributes should be arrays of arrays, value attributes should be an array and parameters should be objects not an array of objects.

A valid response would be as follows:
