Running dredd on petstore does not produce reports due to API Description processing error when processing OpenAPI specification

[stishkin]

Describe the bug

Running dredd on petstore does not produce reports due to API Description processing error when processing OpenAPI specification

To Reproduce

node run C:\Users\statis\node_modules\dredd\build\Dredd.js https://petstore.swagger.io/v2/swagger.json https://petstore.swagger.io --reporter html --output report.html --loglevel debug

Expected behavior
Running dredd from command line on endpoints wth OpenAPI should produce reports.

What is in your dredd.yml?
Running from command line with no yml

What's your dredd --version output?

dredd v14.0.0 (Windows_NT 10.0.19042; x64)
dredd v14.0.0 (Linux 4.15.0-1100-azure; x64)

Does dredd --loglevel=debug uncover something?
Nope

Can you send us failing test in a Pull Request?

Commenting out lines 178 to 181 in Dredd.js skips the early exit.
//if (loggerInfos.find((loggerInfo) => loggerInfo.level === 'error')) {
// callback(new Error('API description processing error'), this.stats);
// return;
// }

That way dredd actually runs and produces reports.
