There was a problem hiding this comment. Is this actually sensitive if it's just the path to a file? There was a problem hiding this comment. 🤷 maybe? The nice thing about making the file sensitive is that the content automatically becomes sensitive. (That's my recollection anyhow) There was a problem hiding this comment. Ok, so there’s some magic there wrt content? If so please keep it as is 👍 |

There was a problem hiding this comment. If these are fed in via extra env, shouldn't they be included in the computed env the resource outputs? (In which case the below would be unnecessary?)

There was a problem hiding this comment. Should we make these optional and let them be provided via extra env too? Would simplify a bit and a user knows they can just cram everything in extra. Right now for url is given here and in extra, what if the values differ? What's the behavior? (IMO maybe it's an error). There was a problem hiding this comment. Alternatively, we could validate at runtime that There was a problem hiding this comment. I agree, that’s what I had in mind, but in a more roundabout way 😅. I think it would help with avoiding mistakes, and remove ambiguity. |
