"No API definition provided." when using swagger-config-file

[RemiBardon]

When providing a swagger-config-file (for example swagger-config.yaml), it's copied as a swagger-config file (without an extension). This file is then used by SwaggerUIBundle in index.html:

// Begin Swagger UI call region
const ui = SwaggerUIBundle({
    configUrl: "swagger-config",
    dom_id: '#swagger-ui'
})
// End Swagger UI call region

(I think) the problem is that when Swagger UI reads the configuration file, it doesn't know what format it's written in (see the documentation about Swagger UI parameters. The resulting Swagger UI is a blank page with "No API definition provided.".

A solution would be to use

const swaggerConfigFileName = basename(config.swaggerConfigFile);
io.cp(
    config.swaggerConfigFile,
    join(config.outputPath, swaggerConfigFileName)
);
return swaggerConfigFileName;

instead of

io.cp(
    config.swaggerConfigFile,
    join(config.outputPath, 'swagger-config')
);
return 'swagger-config';

in swagger-ui-action.ts#L66.
