The best solution is a simple one.
Standard Edition Oracle with Manual Standby generating error – RMAN-06820.
From RMAN-06820 ORA-17629 During Backup at Standby Site (Doc ID 1616074.1):
As of 11.2.0.4, we now include the current standby redo log as part of an RMAN archivelog backup at the standby site.
This is achieved by forcing a log switch at the primary site.
Some options to remedy the issue which seems too complicated.

Backing Up Archived Redo Logs with RMAN
https://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmbckba.htm#BRADV81399
Online Redo Log Switch will occur with backup contains the following clause:
PLUS ARCHIVELOG
ARCHIVELOG ALL
ARCHIVELOG FROM ..
The simple solutions for not switching redo at primary.
Use backup archivelog until time ‘sysdate’ instead of backup archivelog all.
Use backup until sequence instead of from sequence.
Use backup database followed with backup archivelog until time ‘sysdate’.
UPDATE based on comments:
Using RMAN with sys password did not work. This test was not done by me but a teammate and I did not wanted to waste more of client’s time on the matter.
