signandsendTransaction params

1

Hello,

I am trying to call following method

    connection?.signAndSendTransaction(
            String(account),
            AccountTransactionType.Update,
            contractUpdatePayload(CcdAmount.fromMicroCcd(0), contract, 'mint'),
             {
                parameters: mintParameters,schema:typeSchemaFromBase64("8DAQAAABAAAABjaXMyX2R5bmFtaW")
            } 
        );

but get following error

The given transaction is not valid due to: Error: Unable to serialize value due to: Parsing failed
at ob.sendTransaction (chrome-extension://mnnkpffndmickbiakofclnpoiajlegmg/inject.js:14:8000)

The mintParameters is following

const mintParameters = {
        "owner": {
        
         "Account": ["3SfHLNkmy61ZUQkAhMvAwKj47EYDBiUPbn3wHghFD6qGr8WDGc"]
        
       },
    "tokens": [
        [
            "06",
            {
                "metadata_url": [
                    {
                        
                        "hash": {
                            "Some": [

                            ]

            }
        ]

Hi there!

Which contract are you trying to invoke ‘mint’ on? It would be helpful to see the code defining the parameter expected by the endpoint.

3

Hello,

its a dnft example you can see the code here

muniryasir/d-nft_v2 (github.com)

I can execute all methods via cli and sctools.mainnet.concordium.software index is 9583

For front end code i am trying to create a very simple example, I used piggybank as starting point and just trying to pass parameters for mint. to statement above when invoking the contract

I am basically doing the same thing as shown

concordium-smart-contract-tools/front-end-tools/src/writing_to_blockchain.ts at main · Concordium/concordium-smart-contract-tools (github.com)

4

Okay. If you succeed with the parameters supplied when using the concordium client and sc-tools they should be OK. They also look correct when comparing with the source code linked.

Are you sure you’re passing the correct schema to the function? Can you try to give it a module schema instead and see if that works?

5

How do I give it a module schema, pass the schema.bin file?

6

there should be a moduleSchemaFromBase64 function in @concordium/wallet-connectors or @concordium/react-components. You pass this function a base64 representation of the schema.

You might be able to get the base64 string by executing

cat schema.bin | base64

Otherwise you could build the contract with the --schema-base64-out - argument. The - makes it write the schema to stdout, i.e. prints it in your terminal.

I get following

I believe each line represent a schema for different contract method, in react components the method i believe is typeSchemaFromBase64. The error persists

8

Im not sure that each line represents an individual entity in the contract, but I could be wrong. Anyhow, when using the entire module schema you’d have to use the function moduleSchemaFromBase64 to construct the schema parameter instead, as otherwise (if you use typeSchemaFromBase64 ) the function will definitely fail.

9

I ran two tests

  1. One line of Scheme with method moduleSchemaFromBase64 I get following error

Modified code to above, error now

ERROR
The given transaction is not valid due to: Error: Unable to serialize parameters, due to: Unable to find contract schema in module schema

Okay. Can you tell me what is returned when you invoke

contractUpdatePayload(CcdAmount.fromMicroCcd(0), contract, 'mint')

The error could suggest that you’re specifying the wrong contract name for the entrypoint.

Alternatively, we recommend using @concordium/ccd-js-gen to generate a contract client for you for a more frictionless experience when integrating with smart contracts.

It worked the issue was in the method you pointed out and the fix is below

  function contractUpdatePayload(amount: CcdAmount.Type, contract: any, method: string) {
        return {
            amount,
            address: ContractAddress.create(contract.index, 0),
            receiveName: ReceiveName.create(ContractName.fromString(contract.name), EntrypointName.fromString(method)),
            maxContractExecutionEnergy: Energy.create(MAX_CONTRACT_EXECUTION_ENERGY),
        };
    }

I needed to use the ContractName type, otherwise contract name would be undefined, thx for all the help

Great to hear you got it working!
