Review Comment:
I'm not sure is this a good idea to convert everything to string
representation, personally I have no idea how users might use this values later
in case of binary data (or some specific classes)
```python
Python 3.9.10 (main, Feb 25 2022, 16:54:01)
Type 'copyright', 'credits' or 'license' for more information
IPython 8.7.0 -- An enhanced Interactive Python. Type '?' for help.
PyDev console: using IPython 8.7.0
Python 3.9.10 (main, Feb 25 2022, 16:54:01)
[Clang 13.0.0 (clang-1300.0.29.30)] on darwin
import pickle
o = pickle.dumps({"a": 1, "b": 2})
str(o)
Out[4]:
"b'\\x80\\x04\\x95\\x11\\x00\\x00\\x00\\x00\\x00\\x00\\x00}\\x94(\\x8c\\x01a\\x94K\\x01\\x8c\\x01b\\x94K\\x02u.'"
```
It's look like we hide one error and postpone it into the later interaction.
