InvalidLambdaFunctionAssociation: The function ARN must reference a specific function version
Closed this issue · 1 comments
I tried following the documentation for the simple case of adding a trigger to an existing CF distribution. During deployment I'm getting this message:
The function ARN must reference a specific function version. (The ARN must end with the version number.)
The ARN that is being set ends with $LATEST which is an alias, and seems to be unsupported by CloudFront:
arn:aws:lambda:eu-central-1:XXXX:function:XXXX-generateSitemap:$LATEST
What am I doing wrong here?
Btw, I get the exact same message if I manually try to set this ARN by editing the CloudFront distribution in the CF console.
In case someone encounters this in the future:
I noticed the plugin code does have a function that looks for the latest version number. However my serverless.yml had this line:
versionFunctions: false
Which always leaves only the $LATEST version. Changing this value to true fixed the problem.
