Fails on petstore.json service generation

[johndpope]

Using this cannonical json file
https://github.com/OAI/OpenAPI-Specification/blob/master/examples/v2.0/json/petstore.json

The code generation fails

I suspect because the base service specification is mandatory - it's probably my own fault -
but I need some sample base service so that this code generation succeeds.

./generate.sh
yarn run v1.17.3
$ openapi-typescript-client-api-generator -c petstore.json -sb /client/services -s /client/api/services -m /client/api/models -sm /server/modules/api/models

N.B. there are some models spat out successfully.

I did some digging and re-crafted the sample json awesome-api.json

some things that are particular to point out -

this line
"tags" : [ { "name" : "users" } ,{ "name" : "Account" } ], // needed to specify "Account" here to spit out corresponding service

eg.
"paths": {
"/api/Accounts/createAccount": {
"post": {
"tags": [
"Account" // will now spit out account service
],

My expectation though would be to just trawl through the paths and create the corresponding files.
