Format error when using Bosun save hook

Question

I get the following error while attempting to use the "save hook" functionality in Bosun -

failed to call save hook: fork/exec /tools/bosun/bin/save-hook: exec format error. Restoring config: successful

The file is executable and I've removed all logic from it, and the error still occurs.

Should the file return anything? Or is this a bug?
The documentation indicates it should be successful as long as the hook exits ok.

Answer 1

I would guess the OS is not accepting this as a proper executable?

1. If a binary, did you compile it on the same system, or make sure your cross compiled it for the right architecture?

2. If a script, does your script have the bang line at the start, for example #!/bin/bash?
