Replicating tax-bracket fails

[olyashok]

1. Build and deployed everything.
2. Backend up.
3. Schema deployed fine and i got zkDoc address via "yarn hardhat build-deploy-schema --schema /home/node/zkcv/zkdocs/zkdocs-backend/test/test_schemas/tax_bracket.json --network localhost. "
4. Did /home/node/zkcv/zkdocs/cp_script.sh tax_bracket /home/node/zkcv/zkdocs/zkdocs-backend/test/test_schemas/tax_bracket.json
5. Checked zkdocs-ui/src/lib/Config.ts
6. Did ./cp_snarkjs.sh

Still getting this error on Fill form in the client:

Error: Error: call revert exception [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (method="schemaHash()", data="0x", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.6.1)

i can see the contract on ethereal - schemaHash() works fine there - no idea why this call fails in SelectDocWidget.tsx

contract
.schemaHash()
.then(async (schemaHash: string) => {
let schemaMeta = await findSchemaForHash(schemaHash);
if (schemaMeta === undefined) {
setError("No schema found.");
} else {
schemaMeta.contractAddr = contractAddress!;
props.setSchemaMeta(schemaMeta!);
}
})
.catch((err: any) => setError(err));
};

Can you confirm that your wallet is connected to the hardhat testnet?

Any updates on this? I am also having the same error :( @olyashok @sragss

Could you try the new demo instructions? Should simplify the process quite a bit.

I believe this error could only occur due to connecting to the wrong network or entering the wrong zkDoc contract address. Both of those footguns could be mitigated with a more error resistant UI flow.
