undefined is not valid JSON

Hi - I’m sorry at this point I’m not sure what it takes to reproduce, will post if I find out. However sometimes the page errors out with the following logs in the console:

SyntaxError: "undefined" is not valid JSON
   at JSON.parse (<anonymous>)
   at getLoginParams (oidc.ts:199:1)
   at Oidc._callee23$ (oidc.ts:963:1)
   ....
   at localsilentLoginAsync (oidc.ts:961:1)
refreshTokensAsync_silent_error {"message":"exceptionSilent","exception":"\"undefined\" is not valid JSON"}

Do you know what would cause this at all?

Thankyou

I found out how to reproduce this !

1. Have two tabs open, one in the foreground, one in the background (hidden)
2. Ensure the auth server is down / returns an error response when the visible tab refreshes it’s token.
3. Let it retry the 4 times before eventually failing.
4. Now make the second tab visible, and you will see the “undefined” is not valid JSON in that tab’s console.

Ideally, I would like all tabs to recover automatically once the auth sever has recovered… maybe they could continue trying rather than give up after 4 attempts?

Thanks!

Thank you very much for this !

I will fix it as soon as possible. Yes may be retry whithout limit in certain situation may work for this issue.
