[Solved] gateway Error: reactor.core.Exceptions$ErrorCallbackNotImplemented

The production environment is fine, but suddenly all front-end requests are cross-domain and the requests are 500. gateway reports an error.
reactor.core.Exceptions$ErrorCallbackNotImplemented:java.lang.IndexOutOfBoundsException: Index: 0, Size: 0. All interfaces are reported.

}

 

[Solved] Matlab 2021b install activate Error: License manager error – 103

Solution:

After modification, save.

Directly open matlab again, you can succeed!
