My app has been obfuscated using R8, and I've generated a custom exception stack trace. I am using the retrace tool from the command-line tools package along with the mapping.txt to obtain the original stack trace, but it still outputs the obfuscated stack trace.

By comparing the mapping.txt with my stack trace, I can generally pinpoint where the error occurred in the source file, but I still want to use a tool to help me complete this process more quickly. I have searched online for a lot of information but haven't found a solution.

R8 version:8.6.27

Retrace 8.9.21 (build 5e0c90f55d8e11e1f14cdbacdcdb571ac76a1717 from go/r8bot (luci-r8-custom-ci-archive-0-nkew))

my proguard-rules.pro

-keepattributes Exceptions,InnerClasses,Signature,Deprecated,
                SourceFile,LineNumberTable,*Annotation*,EnclosingMethod
-keep class **$$ExternalSyntheticLambda* { *; }
-keepclassmembers class kotlin.Metadata { *; }

my error stack
