NotImplementedError: Unexpected scenario where a(n) OpenBraceToken was not found.

[TylerLeonhardt]

I tried using the latest build today. It looks like generation isn't quite there yet for v3.

The YAML I used is here: https://github.com/TylerLeonhardt/AutoRest-PowerShell-Nodejs-Demo/blob/master/FDIC/fdic.yaml
The original YAML is here: https://banks.data.fdic.gov/docs/swagger.yaml

For now, I'll continue using the node.js generator.

@TylerLeonhardt thanks for reporting this issue. I'm currently investigating and will report back as soon as I get more information.

[joheredi]

@TylerLeonhardt I have merged a fix for the issue you reported. Would you mind trying to generate again using version 6.0.0-dev.20200623.1

[TylerLeonhardt]

@joheredi it looks like it generates but now it requires some kind of credential object?:

new FdicBankDataAPIBeta(credentials: TokenCredential | ServiceClientCredentials, options?: FdicBankDataAPIBetaOptionalParams): FdicBankDataAPIBeta

This API doesn't have any such token/credential (AFAIK)

[joheredi]

If you use the flag --add-credentials=false it should remove the credentials parameter

[TylerLeonhardt]

Something's still not right...

autorest-beta --input-file=https://github.com/TylerLeonhardt/AutoRest-PowerShell-Nodejs-Demo/master/FDIC/fdic.yaml --output-folder=./fdic.ts --add-credentials=false --typescript --use:@autorest/typescript@6.0.0-dev.20200623.1 --v3

# then do

cd fdic.ts
npm install
npm run build
cd ..

Now create a ts file here

import { FdicBankDataAPIBeta } from './fdic.ts/dist/FdicBankDataAPIBeta'

// weird "options: any" as parameter
const myFDIC = new FdicBankDataAPIBeta(null);

myFDIC.searchInstitutions({
    filters: "STALP:NC AND ACTIVE:1 AND CITY:Charlotte",
    limit: 100
}).then(val => console.log(val.data));

and here's my package.json:

  "name": "fdic",
  "author": "Microsoft Corporation",
  "description": "FDICBankDataAPIBeta Library with typescript type definitions for node",
  "version": "1.0.0",

  "homepage": "https://github.com/azure/azure-sdk-for-node",

  },
  "bugs": {
    "url": "https://github.com/azure/azure-sdk-for-node/issues"
  }
}

Using the nodejs generator, I got output from my TS file. Using the typescript generator, I do not get any.

[joheredi]

@TylerLeonhardt is the problem you're describing that your console.log

myFDIC
  .searchInstitutions({
    filters: "STALP:NC AND ACTIVE:1 AND CITY:Charlotte",
    limit: 100,
  })
.then((val) => console.log(val.data));

is logging undefined? If so, would you mind trying the following when creating FdicBankDataAPIBeta:

const myFDIC = new FdicBankDataAPIBeta({
  endpoint: "https://banks.data.fdic.gov/api/",
});

I see that https://banks.data.fdic.gov/api/ is defined in the yaml so I need to investigate why it is not picking it up. But meanwhile it would be helpful if you can help me confirm if this gets you the expected behavior.

As for the any parameter, do you get the same if instead import FdicBankDataAPIBeta this way?

import { FdicBankDataAPIBeta } from "./fdic.ts";

[TylerLeonhardt]

const myFDIC = new FdicBankDataAPIBeta({
  endpoint: "https://banks.data.fdic.gov/api/",
});

This worked!

Also the any parameter goes away when I do that yes:

import { FdicBankDataAPIBeta } from "./fdic.ts";

bit I still need to specify that endpoint in the ctor for it to actually work.

@TylerLeonhardt thanks for reporting these issues. I'm investigating why the server url in the swagger is not being correctly used. The problem seems to be in @azure/core-http. I have filed an issue in its repo to track this Azure/azure-sdk-for-js/issues/9700

I'm going to close this issue as the original problem has been resolved, however feel free to follow the linked Issue, once that one is fixed you should be able to remove the endpoint in the constructor.

[joheredi]

@TylerLeonhardt I have merged a fix which should remove the necessity to pass endpoint to the constructor. The build is 6.0.0-dev.20200625.1 please give it a try

[TylerLeonhardt]

Looks like it works :) thanks!
