When I add a new observer rule to a project with Chrome 90, and I press save, then I expect to be taken back to the project page. Instead, it waits for 60 seconds and then times out, popping up this dialog box:
I edited a second project rule to measure the exact time & capture any messages from console. This is what it reported:
Access to fetch at ‘https://api.inaturalist.org/v1/projects/discord-inaturalist-yearlisting-2021’ from origin ‘https://www.inaturalist.org’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled
When I navigate manually to the project page after that, I can confirm the new observer is successfully saved in the rules.
