Steps to reproduce

0. Generate code with Swagger Hub from yml file (see attached)
1. Download generated code for typescript-angular (see attached)
2. Create new angular project with ng-cli and copy generated code
3. Compile with ng build - see errors in console

Suggest a fix/enhancement

Fix the generated code so that it compiles.

Unpack openapi.zip and typescript-angular-client-generated.zip, then run ng build on the generated client to reproduce the missing-brace error in diary.service.ts at line 229. Compare the generated source with the OpenAPI input and locate the typescript-angular generation template responsible; done when the attached API definition produces code that compiles without manual edits.
