Improve COA creation transaction to gracefully handle existing COA in storage #500
Conversation
WalkthroughThe changes introduce enhancements to the transaction logic for creating a Cadence-owned account, ensuring that if an account already exists for the signer, the process exits early to avoid unnecessary operations. Additionally, error handling in the requester service is improved by providing detailed error messages during the COA resource creation, enhancing robustness and clarity in error management. Changes

13-16: Early exit logic is well-implemented.The check for an existing Cadence-owned account and early exit if found is a good practice to avoid unnecessary operations.
26-29: Proper use of storage saving.Saving the newly created account to storage is done correctly. The path and method used are appropriate for the operation.

191-195: Enhanced error handling in COA creation.The modifications to return detailed error messages instead of just logging them improve the robustness and clarity of the function. This change ensures that errors are properly communicated back to the caller, which is crucial for better error management.

Potential risk with force unwrapping.
Using as! for unwrapping the vault withdrawal could lead to a runtime panic if the cast fails. Consider handling this scenario more gracefully to improve error resilience.
Suggest using a safer casting method or adding error handling around this operation.
Closes: #499
Description
This will allow us to distinguish the actual errors that might arise from the COA creation transaction, as until now we ignored the returned error.
