How to receive the data sent from Angular to C# webapi?

I am sending form data to c# core web api via Angular. Console shows the data being sent via service to the api. I am trying to update a value. However, when debugger is kept at the web api controller, the data shows null. Here is the angular part:

this.commonService.updatescheduleFee(this.flatfeeModel).then((response: ResponseModel) => {
this.toasterMessageService.showSuccess('Fee Schedule Updated Successfully!');
});


Here is the update api being hit with the params:

async updatescheduleFee(params: any) {
params['amount2'] = 100;
console.log('FeeSchedule-params',params);

return await this.ws.put(`${this.billingApiUrl}/invoice/FeeSchedule`,params).toPromise();
}


Here is the api part where model shows null for the values sent via Angular:

[HttpPut("FeeSchedule")]
public async Task<IActionResult> UpdateFeeSchedule(FeeScheduleRequest1Dto model)
{
try
{
}
}


Here is the console screenshot where all the data that is sent to api can be seen:

Any help would be more than appreciable.
