Broken typescript-angular default.service.ts

Description

The generated angular file default.service.ts uses wrong import path delimiters on windows installation.
import { UpdateInfo } from '../model\updateInfo';
Most propably it is using windows path seperator while doing path concatenation, what is not correct way how angular import path should be constructed.

Expected value is import { UpdateInfo } from '../model/updateInfo';

The generated file has also missing } bracket before EOF.

There is missing body parameter in generated post method:
return this.httpClient.post(${this.basePath}/someurl,
body, ---is missing in generated code
{ ....

The import path issue is also in generated api.module.ts containing
import { DefaultService } from './api\default.service';

The generation was invoked by swager-codegen-cli with parameter -l typescript-angular

Start with the typescript-angular generation entry point used by swagger-codegen-cli and compare the generated default.service.ts and api.module.ts shown in the report. Verify the path separators, missing closing brace, and post body parameter against the expected output; done means regenerated files are valid TypeScript with the reported corrections.
