We have a custom Chrome extension that creates buttons in the ADD TO CARD column on the right of open cards on the web interface.
It connects to an internal platform via an API and this stopped working this week.
I am not sure what the cause is but the Chrome console log shows this
Access to XMLHttpRequest at 'https://abc.xyz.com/task?_=1576736887376' from origin 'https://trello.com' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header has a value 'null' that is not equal to the supplied origin.
Please advise how to resolve?
Another Q - if i view source on Trello boards/ cards - there is a "window.trelloVersion = 'build-xxxx';" where xxxx is a number - is this the Trello release updates? How can we see all the details updates that are on these vversions? I found this https://trello.com/b/dQHqCohZ/trello-platform-changelog but it doesn't help to troubleshoot.
Please let me know how I can subscribe to all detailed changes?
@Yatish Madhav CORS is a security feature of the browser, nothing to do with Trello:
