Error: Backend plugin is not valid for dynamic loading: it should either export a BackendFeature or BackendFeatureFactory as default export, or export a const dynamicPluginInstaller: BackendDynamicPluginInstaller field as dynamic loading entrypoint
Expected Behavior
@janus-idp/cli@1.11.1 package export-dynamic-plugin --clean should work as before.

There has been an upstream change https://github.com/backstage/backstage/pull/25098, which is potentially affecting the validate export detection logic of the CLI https://github.com/janus-idp/backstage-plugins/blob/582cf36da48f21f7aa31075430bf566a818a3cfa/packages/cli/src/commands/export-dynamic-plugin/backend-utils.ts#L101-L123.
Sadly this upstream change has been released as a patch release, so everyone locking to
^0.6.xwill soon get this change.Locking the version
"@backstage/backend-plugin-api": "0.6.18"inside thepackage.jsonof the respective plugin fixes the build.
