[Bug] OpenAPI import does not seem to honor default variables in servers declaration

• Insomnia Version: 6.6.2
• Operating System: MacOS mojave 10.14.6

Details

I’m trying to import an OpenAPI 3 spec that uses variables in the server url. Default values are provided for these in the variables declaration. This results in an error when i try to import the file: Invalid URL: http://{host}:{port}/{basePath}

If I replace the url with the following string it works: http://localhost:8080/filemanagement

OpenAPI yaml file (parts of it - but it can be used to reproduce the bug and import works after replacing the servers/url part):

openapi: 3.0.2

Not sure if it is the same or not, but I also can not import OpenAPI to insomnia because of 2 errors.

1. Import failed TypeError: Cannot read property ‘Symbol(Symbol.iterator)’ of undefined
2. failed to import ‘Import failed’ Cannot read property 'map' of undefined. This happens then you press “Import from File” button in a fresh workspace for example.

The first error is also shown when you go to Application > Preferences under “Data” tab and use “Import from clipboard” option.

Sadly, currently it seems impossible to import an OpenAPI spec into insomnia.

Thanks for that @SylannBin! A missing servers declaration wasn’t handled by the openapi3 importer previously, resulting in those errors. I’m willing to say @vitaliis is experiencing the same thing as well.

That has been resolved by #2007 though, and will be included in the next release of Insomnia Core. I confirmed by importing that specification successfully while running on the latest develop.

Also I just wanted to point out that the bug does not occur when you directly copy&paste your openapi.json inside of the Insomnia Rest Designer text editor.

This is because Designer already includes the fix 😄
