they backup is preferred to secondary at present..
This is the default option and backups will occur on a secondary unless the Primary is the only replica online.

Not able to complete the transaction log backup using maintenance plan in principle as it is checking this.

Backup Types Supported on Secondary Replicas--------------------------------------------------------------------------------
•BACKUP DATABASE supports only copy-only full backups of databases, files, or filegroups when it is executed on secondary replicas. Note that copy-only backups do not impact the log chain or clear the differential bitmap.
•Differential backups are not supported on secondary replicas.
•BACKUP LOG supports only regular log backups (the COPY_ONLY option is not supported for log backups on secondary replicas).
A consistent log chain is ensured across log backups taken on any of the replicas (primary or secondary), irrespective of their availability mode (synchronous-commit or asynchronous-commit).
•To back up a secondary database, a secondary replica must be able to communicate with the primary replica and must be SYNCHRONIZED or SYNCHRONIZING.
