Version

1.2.8

What's Wrong?

When upgrading from Doris version 1.2.8 to version 2.0.0, during metadata compatibility testing, after connecting to the FE node, executing SHOW BACKENDSworked normally. However, executing SHOW FRONTENDS resulted in an error: [StmtExecutor.executeByLegacy():767] execute Exception. stmt[2, 422028d2ade449cd-b08684aa0f9b09e8] java.lang.NullPointerException: null.

What You Expected?

If this error occurs, can I still upgrade from version 1.2.8 to version 2.0.0?
