I’m trying to work out how to add permissions to a Lambda’s function policy, to allow it to be invoked by arn:aws:sns:us-east-1:278350005181:daily-aggregated-price-list-api
I tried letting serverless subscribe to this SNS topic directly, but ran in to a permission error (presumably because I don’t own that topic)
I’ve now added a subscription using a resource, but it doesn’t fire, and I assume it’s because the existing function policy doesn’t allow it to be executed by this topic.
Hey @aussiegeek, can you tell me what errors you’re getting? I was able to subscribe to this topic without any issues.
For reference, here’s my
- sns: arn:aws:sns:us-east-1:278350005181:daily-aggregated-price-list-api
Turns out I’d typo’d the arn of the SNS topic, and was hitting invalid name errors, because cloudformation was trying to create a new topic
Nice, good to hear.
I will say I had some issues removing the stack when I was done. I couldn’t call
ListSubscriptions on the SNS topic since I don’t own it, which caused some other problems with the removal process. You might need to manually remove some items.
