Sentry integration - auth failing during build

[NickR49]

Hi there,

I've just converted a CRA app to Next JS and brought it into Vercel. I already had Sentry running using the @sentry/react package and have switched to the @sentry/nextjs package. I've installed the Sentry integration into Vercel. I ran the Sentry wizard in the workspace to populate the config files. On the Sentry side I've enabled the Vercel integration (both 'Vercel' and 'Vercel Internal Integration').

When I push code in my staging branch (which has the new Sentry config) and trigger a deployment I'm now seeing this error -

I have the following env vars set in Vercel -

SENTRY_AUTH_TOKEN
NEXT_PUBLIC_SENTRY_DSN
SENTRY_PROJECT
SENTRY_ORG

I can confirm that the SENTRY_AUTH_TOKEN matches the token in the Sentry 'Vercel Internal Integration'.
Just not sure what exactly is failing. Any ideas of what I can check next?

thanks

I've solved my problem. The Sentry env vars were only exposed to Production builds and not Preview builds
