Can upgradeProxy on polygon mumbai testnet

Support Upgrades
1

Hello,

I'm currently facing issue while using upgradeProxy function in "@openzeppelin/truffle-upgrades".

I use command 'truffle compile --all && truffle migrate --network mumbai'

When 3_deploy_upgrade.js executed, I think upgradeProxy function is not excuted. Just [object Object] is printed in console and not deploy upgradeMyToken contract. But in rinkeby network, it works fine. I'm not sure why I can't upgrade contract on mumbai.

Any clue?

Thanks.

Is there any information on the console other than "[object Object]"? I'm not a mumbai user myself so it's not simple for me to test this.

Even I am also facing the same issue during the polygon mumbai testnet upgradable contract deployment. Is there any solution for this ?
