[SOLVED] Run contract function

Moralis General
#1

Hello.

I am try to use this code with NodeJs:

import Moralis from 'moralis/node.js';
import { EvmChain } from '@moralisweb3/evm-utils';

import oConfig from '../config/index.js';
import { sv, empty, addDebugData, ucfirst, writeToLog, getDateTimeDiff } from '../lib/helpers.js';

const sTokenPairContractAddress = '0xAC6C2a9657Dc4192d85179876E47cd1DE159f616';
const sStreamKey = oConfig.services.moralis.keys.sStreamKey;
const abi = oConfig.oPancakeSwap.oABI.sDefaultContract;
const functionName = 'token0';
const address = sTokenPairContractAddress;
const chain = EvmChain.BSC;

await Moralis.start({apiKey: sStreamKey});

const oResponse = await Moralis.EvmApi.utils.runContractFunction(
{
	abi,
	functionName,
	address,
	chain
});

console.log(' ');
console.log('runContractFunction');
console.log(oResponse.result);
console.log(' ');

and got this error:

/.../@moralisweb3/core/lib/MoralisCoreProvider.js:10
            throw new Error_1.MoralisCoreError({
                  ^

  isMoralisError: true,

}

How I can fix it?

package.json

	"dependencies": {
		...
		"@moralisweb3/core": "^2.7.4",
		"@moralisweb3/evm-utils": "^2.7.4",
		"moralis": "^2.6.7",
		...
	}

Thanks.

It could be a different syntax for using Moralis sdk based on what you are using. You can try to check the documentation for 2 different syntaxes for js and typescript.

I mean the other documentation with the tutorials

#5

Which one? I don’t see another docs …

#6

Another tab on those same docs page.

#7

changed to:

import Moralis from 'moralis';
import { EvmChain } from '@moralisweb3/evm-utils';

import oConfig from '../config/index.js';
import { sv, empty, addDebugData, ucfirst, writeToLog, getDateTimeDiff } from '../lib/helpers.js';

const sTokenPairContractAddress = '0xAC6C2a9657Dc4192d85179876E47cd1DE159f616';
const moralisSecret = oConfig.services.moralis.keys.sSecretKey;
const sStreamKey = oConfig.services.moralis.keys.sStreamKey;
const abi = oConfig.oPancakeSwap.oABI.sDefaultContract;
const functionName = 'token0';
const address = sTokenPairContractAddress;
const chain = EvmChain.BSC;

const runContractFunction = async () => {
	await Moralis.start({apiKey: sStreamKey});

	const oResponse = await Moralis.EvmApi.utils.runContractFunction(
	{
		abi,
		functionName,
		address,
		chain
	});	

	console.log(' ');
	console.log('runContractFunction');
	console.log(oResponse.result);
	console.log(' ');
};

runContractFunction();

The same error.

What are you using to run the script? JavaScript, a module, typescript?

#9

NodeJS vs Module type.

#10

I don’t know what that means. You can try the examples from documentation to see if any of them works for you. For a module it should be a different syntax and the error should be different.

#11

It means that in package.json:

{
    ...
    "type": "module",
    ...
}

and I run this script like:

node /path/to/script.js

I already do it - sent to you screenshot above where I choose example for NodeJS.

The same which in my example above.

#12

That didn’t look like the nodejs

example[quote=“tcolonel, post:7, topic:21186”]
import Moralis from 'moralis';
[/quote]

This looks like typescript

#13

There is another forum post with all the possible versions of importing and using the sdk. There are 3 of them.

#14

https://nodejs.org/api/esm.html#import-expressions

#15

Where? Can u send me the links?

#16

Here it is: Cannot find package '@moralis/sdk'

#17

Didn’t help like this one - [SOLVED] Streams API get Error : Default instance of MoralisCore is not set.

So can you ask support team or give the email address for solve this problem? I have a Business plan if that matter.

Thanks.

#18

You need to do something similar to this (Moralis.default) again in your environment.

If you have, can you post your current code and current error.

#19 
bigint: Failed to load bindings, pure JS will be used (try npm run rebuild?)
#20

You can ignore this, your script should still work.
