在MariaDB 10.5.8上运行Django迁移时出现问题

我一直在尝试从mysql数据库（版本5.7.26-29-31.37-log-output from SELECT version（））迁移到mariadb（版本10.5.8-mariadb-log-output from SELECT version（））

此外，我还看到django并将其从2.2版更新到3.1.5版，因为3.0版正式支持mariadb。有了这个，我还将mysqlclient库更新为2.0.3

但是，在服务器上运行“migrate”命令时，在使用新的DB:decimal.invalidooperation:[]

以下是堆栈跟踪：
