@seaona if you cannot reproduce should we close it?

[seaona]

I've just encountered it again in 12.3.0 and I've seen that there are more than 90k entries for this error in Sentry. So I think that investigating repro steps and trying to address it would definitely help reducing Sentry errors.

We could open the Sentry issue too if that's more helpful to link data, and get more debugging info. What do you think?

Found some repro steps cc @cryptotavares :

Repro:

1. Setup proxy (ie Burpsuite)
2. Intercept the gas.api.cx.metamask.io requests
3. Start a Send flow
4. Leave all the gas API requests unresolved
5. Go to the last confirmation screen
6. Wait a couple of seconds
7. Open the Edit gas
8. See how gas is trying to refresh
9. Confirm tx
10. See background error
