I have to admit an embarrassing mistake on my end on how Bash handles
variables. We are using pydantic to read in various settings from the
environment.
Minimal example of the underlying problem:
pydantic_test.py:
```py
from pydantic_settings import BaseSettings
class A(BaseSettings):
VAR_A: str
VAR_B: str
if __name__ == "__main__":
a = A()
print(f"{a.VAR_A=}")
print(f"{a.VAR_B=}")
```
```
pc@3e4078e998cc:/src$ export VAR_A=abc
pc@3e4078e998cc:/src$ export VAR_B=d$VAR
pc@3e4078e998cc:/src$ python pydantic_test.py
a.VAR_A='abc'
a.VAR_B='d'
pc@3e4078e998cc:/src$ export VAR_B=d\$VAR
pc@3e4078e998cc:/src$ python pydantic_test.py
a.VAR_A='abc'
a.VAR_B='d$VAR'
```
Sorry for the noise 🙏
