Error: getOffchain tips 'this.contract.getAddress is not a function'

[crazyyuan]

After I created EAS instance. Test getAttestation feature is normal. But when I try to getOffchain, some error comes. I printed the EAS instance, the contract has no getAddress function.

version "@ethereum-attestation-service/eas-sdk":"^1.1.0-beta.3"

@crazyyuan Can you please share the chain you're using and also if possible can you share your code repo so we can investigate?

this.contract.getAddress is usually a result of using ethers v5. I'll move ethers v6 as a production dependency to reduce the cases when it happens

[lbeder]

Oh, it's already a production dependency, so something else might have been overriding it

so which ethers version should I set to solve it?

[lbeder]

If you want to use SDK >1.0.0 then you have to use ethers v6
