[Bug]: Cannot convert undefined or null to object

[egorFiNE]

Describe the bug

Sending USDT on BSC to an address crashes MetaMask and makes it unusable even after the restart. I have sent USDT countless times on BSC before so that's a regression of v12.

The way to reset MetaMask is to restart chrome, switch MetaMask to another network, Reset activity, then back to BSC and again Reset activity and only after that I can use MetaMask again.

Bug is 100% repeatable.

Expected behavior

No response

Screenshots/Recordings

Steps to reproduce

1. Open metamask, enter password
2. Go to Tokens tab
3. Select USDT
4. Click Send
5. Choose address in Contacts
6. Enter a positive amount
7. Click Continue

Boom, Cannot convert undefined or null to object

Thanks @egorFiNE

I have attempted to reproduce this but am not able to. Attached is a video of a successful send of USDT, using version 12 of metamask.

Am I following the same steps that you are following?

@danjm I have just recorded a video with the bug reproduction. Can I send it to you by email?

[danjm]

Hey, actually, I think I reproduced it now.

Can you check if the "Show balance and token price checker" toggle in your Settings is off? If so, I think that is required to reproduce this bug.

If you are okay with having that setting turned on, then you can fix the bug by turning the "Show balance and token price checker" setting on, switching networks and then switching back to your desired network.

If you do not want to use MetaMask with that setting turned on, then you will have to wait for us to publish a bug fix.

In any case, please do confirm that setting is toggled off, as it will confirm my understanding of the bug. Thanks again for reporting this and for your help, and sorry for the inconvenience of this bug.

@danjm yeah, that's it. Toggled it on and it works now.
