Suspecting that the problem could be in the new module, I tried to build it and got this error:
$ puppet module build
|
Error: undefined method `split' for nil:NilClass
|
Error: Try 'puppet help module build' for usage
|
Cause
There was a structure error in the metadata.json file of the new module.
It was valid JSON but the dependencies setting was a list of strings instead of a list of hashes.
Wrong dependencies list:
"dependencies": ["other-module"],
|
Solution
Fixing the structure of the module's dependencies in metadata.json made the errors go away and it all worked again.
Correct dependencies list.
"dependencies": [
|
{
|
"name": "other-module"
|
}
|
],
|
