Just got an error this morning after a year of working flawlessly. Chrome tools reports
Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
I know this is related to the legacy lock API migration. I followed the guide and it said all I needed to do was upgrade to the latest lock which I did so I am unclear what I have to do now.
I enabled the legacy lock api in my advanced tenant settings. At first I got “an error has occurred” in the lock popup, but it now seems to be working.
My question is what do I have to do so that this doesn’t stop working in August when the grade period expires?
