I am getting an uncaught promise error from the following code. Does anyone have an idea how should I resolve this error?

Error:
(index):87 Uncaught (in promise) 1073690080
detectFrame @ (index):87
requestAnimationFrame (async)
detectFrame @ (index):86
requestAnimationFrame (async)

Code:

function detectObjects(video, model, canvas) 
        {
            const context = canvas.getContext('2d');
            canvas.width = video.videoWidth;
            canvas.height = video.videoHeight;
            
            async function detectFrame() 
            {
                
                context.clearRect(0, 0, canvas.width, canvas.height);
                context.drawImage(video, 0, 0, canvas.width, canvas.height);
                
                var img = cv.imread(canvas);
                
                //console.log("detect frame trigger");
                //Opencv code here

                requestAnimationFrame(detectFrame);
            }
            
            detectFrame();
        }

        async function main() {
            await loadOpencv();
            const video = await setupCamera();
            const model = await loadModel();
            
            const canvas = document.getElementById('canvas');
            
            detectObjects(video, model, canvas);
        }

I have tried adding Promise to requentAnimation function but I am not able solve it.
