CORS config on the S3 bucket should allow OPTIONS method for a preflight request.

ANSWER : I was calling the api using axios and my method was POST but the problem was in the response header , I was passing a javascript object as application/json , there resides the problem itself i just change it to tex/plain then it works fine .

make sure OPTIONS returns 200 ok by running the curl command.

curl -X OPTIONS -H "Origin: ORIGIN_URL" --verbose API_ENDPOINT

If not then run the below command

aws apigateway update-integration --rest-api-id YOUR_REST_ID --resource-id YOUR_RESOURCE_ID --http-method OPTIONS --patch-operations op='replace',path='/contentHandling',value='CONVERT_TO_TEXT'

and dont forget to redeploy the API
