Per the title, I receive this error:
tyk-gateway_1 | time="Feb 9 01:13:33" level=warning msg="Incorrect key expiry setting detected, correcting"
With a new key, I have found that setting 'never expires' in the dashboard to fix the problem is ineffective until I've set the Expires in the dashboard to some other value (at least "1 month" works), and then set it back.
Once I've set the key to an expiration time I can set 'never expires' and it seems to work (no more error).
I presume this is a dashboard issue.
