Original Pull Request: https://github.com/langgenius/dify/pull/19369

State: closed
Merged: Yes

Summary

Bug fix: During the process configuration, if the process is relatively complex, after multiple node additions and deletions, some edge connection data may become invalid. The source of these edges may point to non - existent nodes. In such cases, null checks are required. Otherwise, trying to retrieve data from an undefined object will result in a TypeError, which can further cause the page to crash due to display issues.
