Error [contracts/oracle.sol:19:39: TypeError: Data location must be "memory"]

[reuniware]

Hello,

When trying to run the sample at https://fravoll.github.io/solidity-patterns/oracle.html
In Remix.Ethereum.Org
I have the following error :

contracts/oracle.sol:19:39: TypeError: Data location must be "memory" for parameter in function, but none was given.
function __callback(bytes32 myid, string result) public {
^-----------^

Try string memory result

Thank you, I'll try that and will let you know if that resolves the issue.

Write " bytes32 memory myid, string memory result ". The problem will solve.

In Solidity, variables declared inside functions are by default in the memory data location, except for variables that represent state (defined outside functions), which are in the storage location.

Solidity requires you to specify the data location (memory or storage) for function parameters if they are of array type or struct type.
So write: " bytes32 memory myid, string memory result ". to solve this problem.
