Cert-issuer -c conf.ini Error

When I run the command I get the following error:
What should I do?

TypeError: CertificateV3Handler.__init__() missing 1 required positional argument: 'app_config'

conf.ini

This looks like an error with Python rather than the library itself.

Did you modify the code?

You need to check why the app_config arg is not passed / available to the function

It worked fine by setting chain to mockchain.Thanks.
If I want to use the originally configured sepolia network, how should I configure it?
I originally defined it like this:

chain = ethereum_sepolia
sepolia_rpc_url = https://eth-sepolia.g.alchemy.com/v2/ALO1O9NVB6XAs9pidhicAfAhZaLRwCKx

issuing_address=0xyourissuingaddress
chain=ethereum_sepolia

in pk_issuer.txt: your private key

Thank you for your reply.
If you continue to specify “ethereum_sepolia” in the “chain” field, the same error below will occur.

😭 cert-issuer -c conf.ini

The conf.ini that is set is below.

If you specify mockchain for chain, it will succeed, but if you change it to ethereum_sepolia, an app_config error will occur.

I solved this by changing the “certificate_handler=CertificateV3Handler()” to “certificate_handler=CertificateV3Handler(app_config)” in python3.10/site-packages/cert_issuer/blockchain_handlers/ethereum/init.py

Thanks so much!!

certificate_handler=CertificateV3Handler(app_config)

After making this modification, it worked!

@lemoustachiste
Is this a bug in cert-issuer?
