One other deceptive error from CloudFormation
This error is sort of proper however principally unhelpful within the specific case I used to be having. I had named some parameters I handed into my template in a fancy approach, to not point out I in all probability want glasses.
I used to be my template again and again and thought I had copied the documentation precisely for FN::Import — even the bizarre caveats.
Lastly I copied and pasted the code from the documentation after which copied and pasted my parameter names into the sub title. That labored.
I feel I in all probability had a typo within the Sub that was referencing a parameter. So the error message is telling me one thing that on this case doesn’t make sense.
It could be extra acceptable to say:
The worth referenced in your Sub doesn't exist on this template. Verify to see that the title you're passing in precisely matches what you're try to reference.
Can also you please repair the bizarre, inconsistent syntax? It’s arduous to recollect how one can create all these one-off circumstances.
Yet one more: I noticed another person received the identical error I’m going the place the FN::Import can’t be on the identical line because the property — a mapping error. The individual responding to them stated “effectively it’s invalid yaml.” So? That is CloudFormation. Overwrite that underlying YAML error message with one thing extra significant within the context of CloudFormation.
