prevent CORS origin error in localhost ( next js)

[nightwolf-041]

hi sir,
i have this CORS error in my localhost when i start next js project :

Access to fetch at 'https://o1023688.ingest.sentry.io/api/5989958/envelope/?sentry_key=b34c74d6d5c44074996dc09add9ceae6&sentry_version=7' from origin 'http://localhost:5000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

how can i prevent this?

Depending on what is causing the envelope to be captured, it'll be one of the options below.

Sentry.init({
  autoSessionTracking: false,
  sendClientReports: false
})

can i put both of these options?

[kamilogorek]

Sure, but make sure it's what you actually want, as autoSessionTracking will disable sessions: https://docs.sentry.io/platforms/javascript/configuration/options/#auto-session-tracking

[nightwolf-041]

does sendClientReports: false effect the logs sent to sentry ?

[kamilogorek]

It prevents sending SDK diagnostics, which won't affect any events from your perspective, only dropped events statistics.

i removed the options and tested again
CORS is gone :) It's so weird

if it comes back, i know what i should to do...
thank you sir, i have no more question
