Issue

Getting errors thrown from this line when doing migrations and using HDWalletProvider connected to infura nodes.

2_deploy_contract.js
=========================

   Deploying 'Contract'
   ----------------------------------
   > transaction hash:    0xtxH4sh
   ⠹ Blocks: 0            Seconds: 0TypeError: Cannot read property 'timestamp' of null
    at Reporter.postDeploy (/../node_modules/truffle/build/webpack:/packages/truffle-reporters/reporters/migrations-V5/reporter.js:317:1)
    at processTicksAndRejections (internal/process/next_tick.js:81:5)
   ⠦ Blocks: 0            Seconds: 0

Migration hangs at this point.

This was likely introduced in https://github.com/trufflesuite/truffle/pull/1868, and is probably due to infura using an array of endpoint nodes, which might not all have the same block state at any given moment.

Steps to Reproduce

Perform a migration using HDWalletProvider, pointed at a public infura endpoint (such as https://ropsten.infura.io/v3/your-key), and observe the above error. It’s sporadic, but has been happening very often for me.

Expected Behavior

I’d expect that the migration does not fail.

Actual Results

See error text above 😃

For anyone else out there in the meantime, downgrading to truffle v5.0.10 allowed me to run migrations against infura without issue.

@adamgall yup, we typically do issue grooming after release. This should be released in v5.0.13 by end of week. Keeping this open for now.
