expo SDK version: 36.0.0
snack-sdk version: 2.3.6
I have a React web client that takes a user’s code and publishes an Expo snack for the user (under a shared account under my control, not to a user’s own Expo account).
The publish fails at two steps with a CORS No 'Access-Control-Allow-Origin' header is present
error:
-
session.sendCodeAsync(files)
-
session.saveAsync()
(same failure as above)
The failures above are coming from http://localhost-studio.code.org:3000
, but the same requests fail in the same way in all environments (production being https://studio.code.org
).
Additional but possibly irrelevant context: Prior to the requests above, requests to session.uploadAssetAsync(downloadedAsset)
complete successfully. Its response includes the header access-control-allow-origin: *
, whereas the responses from the failing requests above obviously do not contain that header.
Am I missing a configuration step? Am I approaching this incorrectly?
I have manual steps that I can supply as well (this feature is available in a production environment behind a feature flag).
Any help is greatly appreciated!
