I have imported an API spec with OAS3 format, which seems to be fully supported by Apigee. When adding and validating the spec file at the embedded editor, everything seems to be fine. When I go to Publish → Portals → APIs → Manage Snapshot, the click on "Update Snapshot" I got the following banner error:
Spec invalid; spec is not valid json or yaml (id: 291540703)
I'm validating the spec with a VSC plugin and directly at the https://editor.swagger.io/, and spec is valid.
