Boolean value is not taking in Postman

[VinayParida]

I was trying to pass a Boolean value in JSON from Postman and every time it gives me this error: "Invalid JSON input: Unrecognized field “isCancellable” (class com.example.springsecurity.dto.AddProductDTO), not marked as ignorable; nested exception is com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field “isCancellable” at [Source: (PushbackInputStream); line: 6, column: 19]

Where this is what I want to input:
{
“isReturnable”: 0
}

I also tried adding ‘false’ instead then it gives me this error: “JSON parse error: Unexpected character (’’’ (code 39)): expected a valid value (JSON String, Number, Array, Object or token ‘null’, ‘true’ or ‘false’); nested exception is com.fasterxml.jackson.core.JsonParseException: Unexpected character (’’’ (code 39)): expected a valid value (JSON String, Number, Array, Object or token ‘null’, ‘true’ or ‘false’)\n at [Source: (PushbackInputStream); line: 6, column: 19]”,

Can anyone help with this?

There is a difference between isReturnable and isCancellable.

Since types are strictly enforced in Java, if you need to send a boolean, send a boolean not an integer.

Also make sure you use this " character for double quotes, not “.

That was bad from my part. I apologize but despite the name it’s a Boolean that I’m sending from my DTO.

And I copied paste the error so that “ came with it

Thank you
