Hardhat 3: Test hangs after entering keystore password (using configVariable + viem + Node)

[Henri-Guillet]

Hi, I'm using Hardhat v3 alpha with Viem and Node.js.

I'm using the integrated keystore feature in Hardhat 3 to protect my RPC URL. I resolve it in my config using:

configVariable("BASE_URL")

When I run a script, everything works as expected:

I'm prompted for the keystore password,

I enter it in the terminal,

the script runs and deploys successfully.

However, when I run a test, I also get prompted for the password, I enter it — but then the test hangs, stuck right after this line:

const { viem, ignition, networkHelpers } = await network.connect("baseFork");

If I hardcode the RPC URL directly in my config instead of using the keystore + configVariable, the test works fine.

Thanks in advance for your help!

Hey @Henri-Guillet, this is a great catch. Thanks for raising it.
I have been able to reproduce the bug locally.
I have opened this issue to track it: #6835
I am going to close this discussion in preference to that issue.
