error minting - invalid private key: invalid length, need 256 bits

[BrwGamer]

This command:
sudo web3 contract call --wait --abi TEST.abi --gas-limit 2000000 --function mint ox...
throws this error:
ERROR: Error calling contract: invalid private key: invalid length, need 256 bits

Even if the variable WEB3_PRIVATE_KEY is set in the environment, I know this because the deploy reads that variable and it works.

Didn't you already ask this in #220 ?

[BrwGamer]

no, this error happens for a different command. As I said, here it don't find the private key even if it is set.

[BrwGamer]

And if I run it without sudo:
web3 contract call --wait --abi TEST.abi --gas-limit 2000000 --function mint ox...
this is the error:
ERROR: error getting ABI: Get "TEST.abi": unsupported protocol scheme ""

[BrwGamer]

Even if I set all permissions to all users to the whole web3 project directory, when calling the mint function this error occurs:
ERROR: Error calling contract: invalid private key: invalid length, need 256 bits
This happens independently of the use of sudo.
The WEB3_PRIVATE_KEY is already stored with export WEB3_PRIVATE_KEY=0x... and inside /etc/environment. The same is for WEB3_ADDRESS.

Thanks

It's either not set or actually invalid. Be sure it's a correct private key.

[BrwGamer]

I'm pretty sure. I just used it to deploy the contract one more time and also to set the account on Metamask.
If I do web3 env it is set correctly.
Also by passing it to the mint command through --pk the error is the same.
What can I do to check?
Thanks

@BrwGamer
See this #223

This should be fixed in latest version.
