代码节点试运行 沙箱报错

不太清楚是为啥，有没有大佬解惑一下

Start by reproducing the code-node trial run described in the issue and compare the result with the attached screenshot. Identify the sandbox error details, including the code-node input and environment, then trace the corresponding execution path. Done means the cause is documented and the sandbox no longer produces the reported error for the reproduced case.
