[GitBox]

hwooson12 opened a new issue, #25295:
URL: https://github.com/apache/airflow/issues/25295

   ### Apache Airflow version
   
   2.3.3 (latest released)
   
   ### What happened
   
   ParamsDict's printable presentation show the class object itself like 
`<airflow.models.param.ParamsDict object at 0x7fd0eba9bb80>` on the page of 
Task Instance Detail because it does not have `__repr__` method in its class.

   It used to be `dict` object and what keys and values Params include are 
shown on UI before replacing Params with the advanced Params by #17100. 
   
   
   
   ### What you think should happen instead
   
   It was originally shown below when it was `dict` object.

   I think it can be fixed by adding `__repr__` method to the class like below.
   
   ```python
   class ParamsDict(dict):
       ...
       def __repr__(self):
           return f"{self.dump()}"
   ```
   
   ### How to reproduce
   
   I guess it all happens on Airflow using 2.2.0+
   
   ### Operating System
   
   Linux, but it's not depending on OS
