AbiError: Parameter decoding error: decoded value is less then minimum for given type

[0xankit]

Expected behavior

for the following code:

pragma solidity ^0.8.0;
    mapping(bytes32 => CredentialSchema) private schemas; // mapping to store schema ID to schema details mapping

function getSchema(bytes32 _guid) public view returns (CredentialSchema memory) {
        require(isSchemaIdExists(_guid) == true, "Schema with this GUID does not exist");
        return schemas[_guid];
    }
// Function to check if a schema ID already exists
    function isSchemaIdExists(bytes32 _guid) private view returns (bool) {
        return schemas[_guid].guid != bytes32(0);
    }

When any existing guid is being passed it returns the correct schema. Following are the tests for above function which works fine while testing through hardhat. i.e It is reverting with the correct message.

it("Should prevent fetching non-existent schema", async function () {
    await expect(
      schemaRegistry.getSchema(schema.guid.replace("a", "b").replace("c", "d"))
    ).to.be.revertedWith("Schema with this GUID does not exist");
  });

Actual behavior

But when being called from web3js it throws AbiError: Parameter decoding error: decoded value is less then minimum for given type

async function getSchemaByGuid(guid) {
  try {
    console.debug("Getting schema by guid: ", guid);
    const result = await schemaRegistryContract.methods.getSchema(guid).call();
    return result;
  } catch (error) {
    throw error;
  }
}
