ORA-65165: missing or invalid path for file creation

I try to create a PDB from SEED. The statement is here:

CREATE PLUGGABLE DATABASE mixedpd1 ADMIN USER mixedpdb1_admin IDENTIFIED BY MixedPdb1_Admin

CREATE_FILE_DEST = '+DATA01/CDB1206/MIXEDPD1/';

ERROR at line 2:

ORA-65165: missing or invalid path for file creation

SQL> host oerr ora 65156

65156, 00000, "pluggable database version %s not allowed"

// *Cause:   An attempt was made to plug in a pluggable database with an

//           incompatible version of the multitenant container database.

// *Action:  Plug in a pluggable database with a compatible version of the

//           multitenant container database.

//

I don't know why the SEED has the incompatible version in the same CDB. How to resolve it?
