The price lookup feature of the CamelotRelayer contract does not work.
The CamelotRelayer contract uses Uniswap V3s OracleLibrary to retrieve price information from Camelot pool. However, Camelot pool does not have the exact same interface as Uniswap V3, so the transaction will be reverted
The getResultWithValidity function of the CamelotRelayer contract calls OracleLibrary.getOldestObservationSecondsAgo and OracleLibrary.consult. And read function of the CamelotRelayer contract calls OracleLibrary.consult .
This is the OracleLibrary code from Uniswap V3. The getOldestObservationSecondsAgo function calls the pool contracts slot0 , observations. The consult function calls the observe function of pool contract.

However, the functions slot0, observations, and observe do not exist in Camelots Pool. I found Camelots pool through CAMELOT_V3_FACTORY (0x1a3c9B1d2F0529D97f2afC5136Cc23e58f1FD35B) at Registry.s.sol.
If you call poolDeployer view function at CAMELOT_V3_FACTORY, it returns 0x6Dd3FB9653B10e806650F107C3B5A0a6fF974F65, and you can see the Pool code in this contract. https://arbiscan.io/address/0x6dd3fb9653b10e806650f107c3b5a0a6ff974f65#code
Dont use Uniswap V3 OracleLibrary for Camelot. You need to implement your own logic to communicate with the Camelot pool. These are functions/variables in Camelot pool that are similar to Uniswap V3 Pools.
