I had received this error
TypeError: Cannot convert undefined or null to object
after I wrote something like this
@IsArray() @ArrayNotEmpty() @ValidateNested({ each: true }) @Type(() => UserDto) items: UserDto[]
Why its does not work for me 😢
Are you sure that items property is not null / undefined? Maybe it didn't come in the request?
Finally I knew why it wasn't work for me. Because I wrote nested object in array more than couple layers. By the way I have fixed it by customized validate pipe when it received bad request exception. Now it works for me!
Can you share your code?
i was able to solve this problem with the help of custom recursive function in global validation pipe like this:
helper.js
and in main.ts
