Same here on the latest version

We're facing the same issue. We have been supplied three swagger.json files and only one of them can get imported.

[alxpsr]

any progress? 🙄

I have tried to import the following Swagger 2.0 spec without success: "No importes found for file"

https://raw.githubusercontent.com/Azure/azure-rest-api-specs/master/specification/containerservice/resource-manager/Microsoft.ContainerService/stable/2019-02-01/managedClusters.json

[Dracer5]

A lot of people experiencing with bug, me too. Will you provide further info?

[gschier]

Just took a look at this and it seems like $ref attributes are causing the issues.

@alxpsr's example file returns the following error:

Error resolving $ref pointer "/Users/gschier/Workspace/insomnia/desktop/packages/insomnia-app/#/definitions/Dto.Document.DocumetnDto". 
Token "definitions" does not exist.

@dominik-lekse's example returns the following error:

Error opening file "/Users/gschier/Workspace/insomnia/desktop/packages/insomnia-app/examples/ManagedClustersList.json" 
ENOENT: no such file or directory, open '/Users/gschier/Workspace/insomnia/desktop/packages/insomnia-app/examples/ManagedClustersList.json'

It looks like $refs are only for linking to documentation reference so there errors probably should be ignored. I just refactored the import module to try continuing if the Swagger validation fails. This should fix the problem I think.

[gschier]

Also, thank you @alxpsr and @dominik-lekse for the test case files. I've included @alxpsr's example in the test suite fixtures

I figured out that there is the same bug in OpenAPI importer (openapi3.js). Here is the output of my console:

openapi3.js?9a64:87 SyntaxError: Error resolving $ref pointer "/(...)/insomnia/packages/insomnia-app/#/components/schemas/api-version". 

I guess we could apply the same fix ?

[rmedaer]

Here is my patch for OpenAPI3: #1515
