Client Request Processing Errors | ||
AXONIQ-1000 | AUTHENTICATION_TOKEN_MISSING This indicates that the Axon Server has been configured with authentication enabled and a client application did not pass a token. | |
AXONIQ-1001 | AUTHENTICATION_INVALID_TOKEN This indicates that the Axon Server has been configured with authentication enabled and a client application has supplied an invalid token. | |
