"Provider not set or invalid." Error after transition from 1.0.0-beta.24 to 1.0.0-beta.27

[mjhm]

This sample app works: https://github.com/mjhm/hello_world_dapp. (See README.md for install/run steps.)

UPDATE: I updated the example with the workaround mentioned below, so now the bug is exposed by removing this line https://github.com/mjhm/hello_world_dapp/blob/master/server.js#L55

However upgrading web3 from 1.0.0-beta.24 to 1.0.0-beta.27 causes it to fail

I'm pretty sure it was working for 1.0.0-beta.26 since I tried that out last week. Unfortunately I can't easily revert to that version because it appears the the sub modules all automatically upgrade to 1.0.0-beta.27

See the package-lock.json for the working version manifest.

So far it looks like I'm being tripped up by the changes from #1191

[mjhm]

So it looks like Contract.deploy(...).send() creates a new contract instance but doesn't copy the provider to that instance. I can work around the issue with an explicit newContractInstance.setProvider(<original provider>), but this seems like something that should be fixed.

I have run into this today, thanks for the quick workaround. If I were more into this, I would question the need of every Contract to have its separate Provider, but I guess it is too late now.

[MrTibbles]

I to ran into this. Pesky bugger.

[mjhm]

Still broken with version 1.0.0-beta.29

[awgneo]

+1 to broken still in 1.0.0-beta.29

[Thomas-K-John]

Yes.. I am also having this issue in [email protected]. Thanks for the workaround.

[Toeplitz]

Interesting bug? Thanks for this issue helping me out.

[frozeman]

[mjhm]

Confirmed fixed. Thanks.
