I created one Rum Test page for nginx with RUM script. curl command is working and giving output 202

command curl -v -X POST htt://10.xx.xx.xx:8200/intake/v2/rum/events -H "Origin: htt://corporateoperation.xx.co.in" -H "Content-Type: application/x-ndjson" --data-binary $'{"metadata":{"service":{"name":"test-rum","agent":{"name":"rum-js","version":"5.13.0"}},"user\_agent":{"original":"curl"}}}\n{"transaction":{"id":"abc123","trace\_id":"abc456def7890123","type":"page-load","duration":123,"name":"Test Transaction","timestamp":1691496540000000,"span\_count":{"started":1}}}'

But when i tried with RUM test page in my local machine then got “Failed sending events: signal is aborted without reason”
