ChainLink Any API Large Response Example doesnt fulfill

I took the example from the official ChainLink Any API Large Response docs and deployed it to the kovan network without any changes.

The contract: https://kovan.etherscan.io/address/0x1B0beB43a03591bc7f8B5eFf1F0bfB8400e12a63
Compiler: 0.8.7+commit.e28d00a7

I also verified it's code to be sure that it matches with the example from docs, fund it with 2 LINK tokens. Then I called requestBytes method twice, one 8 hours ago and another 7 hours ago:

Both finished without any errors, but when i'm reading data and image_url they're empty:

Getting uint256 works fine, the problem arises only with Large Responses.

That demo broke due to API changes in the ChainlinkClient and Operator.sol contracts.

The demo has now been updated and should work. Note that the function for sending the Chainlink request has changed to sendOperatorRequest() (for large response requests.)
