【问题描述】（请对问题进行描述，方便定位问题）
When modifying configurations to start a node, I encountered an error in the exception handling message that included %+v. Normally, this should be part of a formatted string, and if matched properly, it should not appear in the printed output.
After analyzing the exception stack step by step, I located the issue at /root/go/pkg/mod/chainmaker.org/chainmaker/consensus-maxbft/v2@v2.3.5/epoch/epoch.go:114. The problem occurs in line 114, where the method e.log.Panic is used for output. This method does not format strings but directly outputs comma-separated contents.
The e.log object has another method, Panicf, which can format strings for output. Replacing Panic with Panicf would allow the output to be formatted properly.
