puppet error stack level too deep Report processor failed: undefined method `[]’ for nil:NilClass
In my case I was getting
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: stack level too deep
Warning: Not using cache on failed catalog
Error: Could not retrieve catalog; skipping run
I did mistake in my manifest where I called node within node
e.g.
node apache_template inhirets apache_template {
}
This was causing continues loop and causing stack level too deep error message. Needed to remove that typo or by providing correct node to be inhirited. 🙂
