[Error] Unable to determine version. Make sure to include `release` - sentry/gatsby + Cloudflare

[next grotto]

Hello team!

I am trying to install Sentry in my Gatsby (4.6) application with Cloudflare pages.

I have configured the Sentry plugin in gatsby-config such as:
{
resolve: "@sentry/gatsby",
options: {
dsn: "https://xxxxx",
release: process.env.CF_PAGES_COMMIT_SHA
}
},

But my builds are stll failing in cloudflare:
Sentry CLI Plugin: Unable to determine version. Make sure to include release
09:47:55.387 option or use the environment that supports auto-detection
09:47:55.388 https://docs.sentry.io/cli/releases/#creating-releases

I would set the SENTRY_RELEASE environmental variable, is that possible to configure?

Hello Abhi, thank you for your prompt reply!
Yes, but what value should SENTRY_RELEASE take here? Isn't it supposed to be dynamic?

[neat jacinth]

our Gatsby SDK unfortunately uses v1 of the sentry webpack plugin, which doesn't have good release discovery for cloudflare pages

in v8 we are trying to fix this by bumping to v2 of the plugin

SENTRY_RELEASE should map to whatever CF_PAGES_COMMIT_SHA is

so the webpack plugin can pick that up
