I'm trying to pass a string[] from node.js to solidity function:

function test(string[] memory options) public {}

like this way:

const options = ["a","b","c"]
const contract = this.getContract();
const testFunc = contract.functions['test'];
await testFunc(options);

but got the error: invalid value for array;

Solidity pragma:

pragma solidity 0.6.5; pragma experimental ABIEncoderV2;

Also, if I call a contract from Etherscan with the same value it works

contract.functions is used in ethers.js (docs). Since your question is tagged web3, my answer is using the web3 library.

Assuming that this.getContract() returns the Contract instance, you can execute a contract method using the contract.methods (docs) object.

Use .send() to send a read-write transaction from your configured wallet, or .call() to make a read-only call.

const options = ["a","b","c"]
const contract = this.getContract();
await contract.methods.test(options).send();
