Christopher Boyd · Answer

I m not sure if it s something that changed in container or in the build or elsewhere checking Pydantic <https docs pydantic dev dev v2 changelog v1100 2022 08 30> ```v1 10 0 2022 08 30 Adds the SecretField abstract class so that all the current and future secret fields like SecretStr and SecretBytes will derive from it 3409 by expobrain```
