About the source map of RUM

I successfully collected monitoring data in my frontend project (react). Now I use the serverUrl I got from inti to upload the map file, but this link seems to be 404 all the time. This problem has been bothering me for a long time. If someone can answer it, I will be very grateful. https://80efe80488d24b3b8b6ac70b0f7858b2.apm.eu-west-1.aws.cloud.es.io:443/(serverUrl + /api/apm/sourcemaps)
