Hi @gangadharswami, this is because we dropped support for SDK33 when we released SDK 37 this week. We routinely drop SDK versions that have low usage in order to reduce the number of versions that we need to support.
As usual, standalone apps built with SDK 33 will continue to work; however, SDK 33 projects will no longer work within the latest version of the Expo client.
If you want to re-run expo build, you’ll need to upgrade from SDK 33, preferably to SDK 37 so you won’t need to update again for a while (and also because each Expo version is better than the last!).
Each SDK’s release notes have upgrade instructions. Strongly recommend that you upgrade one version at a time to prevent any issues. Skipping upgrades on any kind of software is dangerous business – take it from someone who once wound up sobbing in front of an Apple store because she skipped a version during upgrade.
That is:
Start by upgrading to SDK34, following the upgrade instructions and minding the breaking changes that are listed in the SDK34 release notes.
