Sentry not being on sentry board after upgrading sentry/node to v7.x.x

[Amangiri99]

Recently we made an update to our sentry packages that includes: sentry/node, sentry/integrations after the update I found that the sentries were not being sent to the sentry board.
I tried running the sentry in debug mode and here's the warning message that I have been getting: Sentry Logger [warn]: Sentry responded with status code 403 to sent event.

Do let me know what should I do in order to get this messages captured.
For the time being I have downgraded to a lower version: 6.x.x and everything seems to be working as expected.
