``render_template_as_native_obj=True,`` will force to use
`jinja2.nativetypes.NativeEnvironment` which are enforced to convert some to
python types, see example:
```python
from jinja2.sandbox import SandboxedEnvironment
from jinja2.nativetypes import NativeEnvironment
environments = {"sandboxed": SandboxedEnvironment(), "native":
NativeEnvironment()}
template = "4.0"
for name, env in environments.items():
print(f" Jinja2 Environment: {name} ".center(72, "="))
rendered = env.from_string("4.0").render()
print(f"Template: {template!r}")
print(f"Rendered: {rendered!r}, Type: {type(rendered).__name__!r}")
```
```console
==================== Jinja2 Environment: sandboxed =====================
Template: '4.0'
Rendered: '4.0', Type: 'str'
====================== Jinja2 Environment: native ======================
Template: '4.0'
Rendered: 4.0, Type: 'float'
```
There is two options here.
**Option 1**:
Do not use `jinja2.nativetypes.NativeEnvironment`, e.g.
`render_template_as_native_obj=True`
**Option 2** (Airflow 2.8+):
Use `airflow.template.templater.LiteralValue` (see:
https://github.com/apache/airflow/pull/35017) wrapper, which prevent template
values, e.g.
```diff
+from airflow.template.templater import LiteralValue
...
create_job_kwargs={
'WorkerType': 'G.2X',
'NumberOfWorkers': '1',
'DefaultArguments': {
'--datalake-formats': 'iceberg',
'--additional-python-modules': 'importlib',
},
- 'GlueVersion': '4.0'
+ 'GlueVersion': LiteralValue('4.0')
},
```
