Getting invalid release version error in Sentry portal

When drilling into each event listed in the Sentry/Issues page, I see a warning message like: “There were 3 errors encountered while processing this event.”

One of those errors is:

  • release: Discarded invalid value
  • Reason: Invalid characters in string

Our release string follows this format: “@repo/our-project@year.week.build”

Can someone please explain why this is considered invalid?
