@meichhorn-conet Would you provide more details about how to reproduce the issue?

[meichhorn-conet]

How can I turn on advanced logging so that i can see which class is current processed and leads to this error?

Not just logs. I need steps to reproduce issue. Generally speaking please provider swagger, and how you generate the module.

[bgrossman]

First time using AutoRest, getting the error too. Using this OpenAPI spec. Generating with:

autorest --powershell --input-file:openapi.json --output-folder:foo

[meichhorn-conet]

@dolauli In my case, i cannot share the whole schema.json because this a private api.

The stacktrace says a single class cant be generated. With that class name, i can try reproduce this error with a simple api and without ip.

how can i turn on this log to get the class name?

Log will not help lot here. You will not need to provide your private swagger to me, but you could just write a swagger that could reproduce the issue and meanwhile hiding your business info.

I'm getting basically the same error for this Azure DevOps Artifacts Feed swagger.

I run this command autorest --input-file=feed.json --powershell --verbose

I get this error:

error   | Autorest completed with an error. If you think the error message is unclear, or is a bug, please declare an issues at https://github.com/Azure/autorest/issues with the error message you are seeing.

Is there some way to get a better error message? I feel like it's common to get errors but not sure if it's the tool or the swaggers/openapi specs that are at fault. Either way it would be nice if the tool didn't crash if it can't complete everything, if just one route or model is wrong in the whole spec then it could be a warning instead perhaps?
