Validators IsNumber() inside an array of objects does not work in NestJS-CodePudding

I want to implement a validators for my class. I have two class and one of these is called as array of object in one of my class attribute: enter image description here When I try to send the json through postman, the validators tells me that: must be a number conforming to the specified constraints This is my ValidationPipe in the main.ts:

app.useGlobalPipes(
new ValidationPipe({
  disableErrorMessages: false,
  enableDebugMessages: true,
}));

And this is my method in controller:

@UseGuards(AuthGuard)
@Post()
async create(@Body() createDiscussion: CreateDiscussionDto): Promise<Discussion> {
  return await this.discussionService.createDiscussion(createDiscussion);
}

How is this possibile if I'm sending the value as number? Thanks

I expect that the error message will disappear and works when I really send a not number value.

CodePudding user response：

The problem doesn't come from your codebase. It actually comes from your request body.

When you take a deeper look at the JSON from your Postman request, there is a : character inside the property name "like:": while it should just be "like":.
