Boolean query param is parsed in development but not in production??

[dark lava]

Hello, I already fixed this issue, but I still don't understand what's going on.

I have a boolean query param like this:

@Query('checked') checked: boolean

There is no ParseBoolPipe yet, but this works while in development (npm run start:dev). I get a boolean with console.log(typeof checked).

Now, as a developer I see this and push it to production, where it breaks. In production the console.log shows string.

Why? I fixed it by adding a new ParseBoolPipe() but I don't understand why the difference in behaviour without a warning.

just having that
@Query('checked') checked: boolean
isn't enough to parse query parameters

you must use ParseBoolPipe or something like that

hi, but it works in development, that's what I don't understand

without the pipe it actually works

but running npm run start:prod the result is different:

I can only think that the development server is doing something aditional
