Getting queueItemParameters must not be null

We have seen the queueItemParameters must not be null off late like almost 3 weeks onwards. Same thing was working before.
We are generating token with below
https://account.uipath.com/oauth/token
{
“grant_type”: “refresh_token”,
“client_id”: “8DEv1AMNXczW3y4U15LL3jYf62jK93n5”,
“refresh_token”: “TttXEegUnMp9CsGbiiicacV9SsodlZHketQbIODaDX9ou”
}
Same access token being to add the queue item

}
}
}
When we try to send it returns below error message
{
“message”: “queueItemParameters must not be null”,
“errorCode”: 0,
“traceId”: “00-c6efa9a6fbaa1ecd52793d3d5ace124a-a05cf076e486c2c7-00”
}
We have check the documentation but do not see any difference

Can someone help here as I am block and not able to proceed.

@Amol_Datar1,

Try out these solutions if not already.

Thanks already tried that but actual issue got resolved with below changes, had to use String instead of string

Oh ok. It’s case sensitive :face_with_peeking_eye:
