### Apache Airflow version

2.6.2

### What happened

If I want see the common information of the N mapped task .

I edit manually the URL cause there is no button in the current airflow console 

```url
http://localhost:8090/task?dag_id=kubernetes_dag&task_id=task-one&execution_date=2023-06-18T00%3A00%3A00%2B00%3A00&map_index=0
```

by removing the `&map_index=0`

if I click on `rendered-templates` it fail

```log
{app.py:1744} ERROR - Exception on /rendered-templates [GET]
