Cannot construct transaction: unknown consensus protocol when using goal clerk send

post by alberkom on Aug 20, 2020

Running a participation node on MainNet.

When trying to send some algos using goal clerk send I’m getting the following error:

cannot construct transaction: unknown consensus protocol https://github.com/algorandfoundation/specs/tree/e5f565421d720c6f75cdd186f7098495caf9101f

however I’ve updated my node to the latest version and it is in sync using the required consensus protocol:

I could confirm this by running goal node status:

Last committed block: 8584910

Time since last block: 4.1s

Sync Time: 0.0s

Last consensus protocol: https://github.com/algorandfoundation/specs/tree/e5f565421d720c6f75cdd186f7098495caf9101f

Next consensus protocol: https://github.com/algorandfoundation/specs/tree/e5f565421d720c6f75cdd186f7098495caf9101f

Round for next consensus protocol: 8584911

Next consensus protocol supported: true

Genesis ID: mainnet-v1.0

Genesis hash: wGHE2Pwdvd7S12BL5FaOP20EGYesN73ktiC1qzkkit8=

Am I missing something here?

Any help is much appreciated.

Can you post the command you used?

Hi Jason, thank you for your reply. I manage to fix the issue using ./ before the command:

./goal clerk send

Can you run:

./goal version -v
./algod -v

One issue might be that you have installed the software in multiple places and ./goal is not the same version as of the goal command running the node.

Hi fabrice, thanks for your reply. What you describe is exactly what was happening.

./goal from the latest install location fixed the unknown consensus protocol issue. Cheers.
