:trishul.goel any chance you could take a look? Thank you.

Hi Natalia,
I tried to look into this, but was unable to get any pointers.
I ran the mochitest with latest tip and was not able to get this error.

Hi Trishul, to reproduce you can try the following steps:

Flags: needinfo?(trishul.goel)

By any chance does this require access to try server? as I don't have it

Flags: needinfo?(trishul.goel)

Trishul, if you don't have access to try we can test the patch for you on the daily beta-sims we're doing.

Hi Cosmin, as mentioned in #c1 I am not able to reproduce this issue.

Flags: needinfo?(trishul.goel)

Only observed with last Saturday's central-as-beta simulation.
