Zanie · Answer

Hey Henry are you setting any custom environment variables config or connection urls

Henry · Answer

i don t believe so

Henry · Answer

my mistake it looks like this stackoverflow issue was correct

Henry · Answer

the `sqlalchemy dialects postgres` is referenced by the `postgres ` URI

Henry · Answer

so using `postgresql ` fixes it

Zanie · Answer

Yeah that is my suspicion as well

Zanie · Answer

We should be setting that correctly in our images though

Henry · Answer
