Injection of current folder path into TypeScript file

I’m using nswag run /runtime:NetCore31 with the below nswag.json config file. In the settings for the openApiToTypeScriptClient code generator, when I added the value for extensionCode it does prepend the imports for the base classes to the file, but at the end of the file, just before the closing brace, it also injects a line of code that is the current file path (which results in code that doesn’t work).

Adding // to the beginning (or the end) didn’t work for me… but adding /* fix bug */ to the beginning did. Resulting line for extension code looks like this:

"extensionCode": "/* fix bug */ import { BaseClient, ClientOptions } from './base';",

This adds the import to the top where it belongs and then adds a line with the comment before the closing bracket in the file:

/* fix bug */
}

Yes, it is definitely using the extensionCode property that introduced the issue I reported. Another interesting thing is that on Windows, when it inserts the import statement it changes ‘./base’ to ‘\base’ which is another bug.

I changed my usage to instead have the fix-index postgenerate script insert the import statement and I stopped using extensionCode.
