Bug Description

Parameters serialization fails with the error Unable to serialize parameters, due to: Unable to find contract schema in module schema

Steps to Reproduce

import {
    serializeUpdateContractParameters,
} from '@concordium/node-sdk';

const BALANCEOF_FUNCTION_RAW_SCHEMA = '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';

                address: {
                    Account: [account],
                },
                token_id: '',

        ],
        rawSchema,
    );

copied from https://github.com/Concordium/concordium-browser-wallet/blob/main/examples/wCCD/src/wCCD.tsx updateWCCDBalanceAccount function, and just changed toBuffer to node's Buffer.from

throws

Error: Unable to serialize parameters, due to: Unable to find contract schema in module schema

Expected Result To not throw error, and serialize as usual

Actual Result Throws error. Could anyone point out what I'm doing wrong?

The function you're trying to use takes the schema of a contract module, whereas the name of your schema constant indicates you specify the schema for a function (perhaps it's parameters?). If this assumption is correct, this will likely be why it fails.

If you want to use the schema for a functions parameters, please try using the function serializeTypeValue instead.

I didn't change anything, and it got fixed somehow now it works.
