ERC721: transfer caller is not owner nor approved -- Potential issue with vm.prank?

[omeguhh]

I am writing a stake function and testing with forge. Please see code below:

function stake(uint256 _tokenId) public nonReentrant {
        require(stakedNft.ownerOf(_tokenId) == msg.sender, "You don't own this token.");
        if(stakers[msg.sender].amountStaked > 0) {
            uint256 rewards = calculateRewards(msg.sender);
            stakers[msg.sender].unclaimedRewards += rewards;
        }
        //stakedNft.approve(address(this), _tokenId);

        //this.onERC721Received(address(this), msg.sender, _tokenId, "");
        stakedNft.safeTransferFrom(msg.sender, address(this), _tokenId);

        StakedToken memory stakedToken = StakedToken(msg.sender, _tokenId);

        stakers[msg.sender].stakedTokens.push(stakedToken);
        stakers[msg.sender].amountStaked++;

        stakerAddress[_tokenId] = msg.sender;

        stakers[msg.sender].timeOfLastUpdate = block.timestamp;
    }

TEST:

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.13;

import "forge-std/Test.sol";
import "../src/DPDepositor.sol";

contract DPDepositorTest is Test {

    DPDepositor depositor;
    IERC20 immutable CeoTokenTest = IERC20(0x5FbDB2315678afecb367f032d93F642f64180aa3);
    IERC721 immutable dpGenOne = IERC721(0xede855ceD3e5A59Aaa267aBdDdB0dB21CCFE5072);
    address public owner = /*[FAKEADDRESS]*/;
    function setUp() public {
        depositor = new DPDepositor(CeoTokenTest,dpGenOne);

    }

    function testPepeHolderCanStake() public {
        vm.prank(owner);
        depositor.stake(780);
    }
}

The problem i'm getting is that my function works all the way until I hit safeTransferFrom. But I spent time on stack overflow and open zeppelin docs as well as watching some tutorials and couldn't find anything wrong with my contract so I was wondering if it could be vm.prank?

The reason I think that might be the case is that according to openzeppelin the approve function checks to see if ERC721.ownerOf(tokenId) == msg.sender and my stake function also uses a require statement to check for this. However, my test fails when trying to call approve or safeTransferFrom even though my msg.sender is the owner of the specific nft.

Thanks for the assistance here!

Figured it out. Had to add

vm.startPrank(owner);
dpGenOne.setApprovalForAll(address(depositor), true);

In the test function. All good, thanks!
