All API endpoints of spring boot returns 404 NOT FOUND error after obfuscation using Proguard

Question

I have an application with over 100 endpoints, all of which were working perfectly before obfuscation. However, after obfuscation, none of the endpoints are working. All of them return a 404 error.

Here is the obfuscation configuration I used:

-target 11 ##Specify the java version number
-dontshrink ##Default is enabled, here the shrink is turned off, that is, the unused classes/members are not deleted.
-dontoptimize ##Default is enabled, here to turn off bytecode level optimization
-useuniqueclassmembernames ## Take a unique strategy for confusing the naming of class members
-adaptclassstrings ## After confusing the class name, replace it with a place like Class.forName('className')
-adaptresourcefilecontents **.properties,META-INF/MANIFEST.MF
-dontnote
-repackageclasses foo.main
#-dontpreverify
-ignorewarnings ## warnings are ignored
#-dontwarn
#-keep public class * extends org.springframework.boot.web.support.SpringBootServletInitializer
-keep class java.lang.invoke.StringConcatFactory { *; }
-applymapping mapping.txt
-keepdirectories ## Keep the package structure
-keepclasseswithmembers public class * { public static void main(java.lang.String[]);} ##Maintain the class of the main method and its method name
-keepclassmembers enum * { *; }  ##Reserving enumeration members and methods
-keepclassmembers class * {

}

project structure after obfuscation

Can someone help me understand what might be causing this issue?

I tried running the unobfuscated jar and it worked fine. I suspect that there might be some issue with the obfuscation process that I used.
