CORS error when trying to upload via presigned url from browser, but not in non-browser environment

I'm trying to generate s3 presigned url to upload video/mp4 files to a bucket from react app client in development mode in my localhost. However, I'm getting CORS error. But when I do the put request from a python script it goes through, which establishes that my presigned url is working.

This is how I'm generating presigned url through a lambda:

import os
import boto3
from botocore.exceptions import NoCredentialsError
import uuid
import json

def handler(event, context):
    bucket_name = os.environ['BUCKET_NAME']
    object_name = str(uuid.uuid4())+ ".mp4"
    aws_region = "eu-west-1"
    s3_client = boto3.client('s3', region_name=aws_region)


    try:
        response = s3_client.generate_presigned_url('put_object',
                                                    Params={'Bucket': bucket_name,
                                                            'Key': object_name,
                                                            'ContentType': 'video/mp4'
                                                            },
                                                    ExpiresIn=3600,
                                                    HttpMethod='PUT',
                                                    )
    except NoCredentialsError:
        return {
            'statusCode': 400,
            'body': 'No AWS credentials found'
        }

    return {
        'statusCode': 200,
        'body': json.dumps({
            'upload_url': response,
            'object_name': object_name
        })
    }

This is my how my client react app is making the request:

const uploadFile = async (file: File) => {
        setUploading(true);
        setUploadSuccess(null);

        const formData = new FormData();
        formData.append("file", file);

        try {
            // gets the presigned URL for uploading the file via lambda function url
            const uploadUrl: string = await axios
                .get(
                    "https://somethingsomething.lambda-url.eu-west-1.on.aws/",
                )
                .then((response) => response.data.upload_url);


            // uploads the file to the presigned URL
            const response = await axios.put(uploadUrl, file, {
                headers: {
                    "content-type": file.type,
                },
            });
            
            if (response.status === 200) {
                setUploadSuccess(true);
            } else {
                setError("Upload failed. Please try again.");
                setUploadSuccess(false);
            }
        } catch (error) {
            setError("Upload failed. Please try again.");
            console.error(error);
            setUploadSuccess(false);
        } finally {
            setUploading(false);
        }
    };

This is the CORS configuration on the S3 bucket: Error in Chrome console: Preflight option request and response header: Error in Firefox console: Network tab in Firefox: Error when opened:
