Ethereal-O opened a new issue, #329: URL: https://github.com/apache/incubator-hugegraph-computer/issues/329
### Feature Description (功能描述) When retrieving servers from an array, nil may occur and needs to be addressed. There are several options to choose from: 1. In obtaining the server function, simply output a prompt to the user Advantages: Compared to errors, it has more obvious information. Disadvantage: There is basically no processing, and errors will still occur when sending messages to the client in the future. 2. In the server function, return a default object that can execute the function without throwing an error, but can output prompt information Advantages: Unified processing, no need to modify a large amount of code. Disadvantage: It depends on the error handling mechanism of subsequent code. 3. Modify all calls to consider the issue of nil pointer Advantages: A relatively complete error handling mechanism. Disadvantage: There are too many logical changes that need to be made, and they are too repetitive. I am a newcomer and I am not sure what the best option is. Do you have any suggestions? thank. https://github.com/apache/incubator-hugegraph-computer/blob/1765fd9ebf6538b408f662b0a014d4b93053ced7/vermeer/apps/master/bl/server_manager.go#L81 -- This is an automated message from the Apache Git Service.
