Elasticsearch-curator 5.8.2 is failing during TypeError: load() missing 1 required positional argument: 'Loader'

Elastic Stack Elasticsearch

Hello,

I'm trying to execute a dry run for delete snapshot when I got this error: TypeError: load() missing 1 required positional argument: 'Loader'

Note that it worked before (like 5 days ago). It started failing after we upgraded our production system PyYAML to 6. Is there a curator version that works with PyYAML 6 (AND it should also work with Elasticsearch 5.6.17)?
Will really appreciate your help!

Thank you!

Error:

Self diagnosis:

  1. I came accross this issue: Delete_snapshot action fails, get() takes at least 2 arguments (2 given)
    but I don't see any resolution? forgive me if I have missed it somewhere?

  2. some sites are suggesting that I should downgrade my pyyaml to 5.x.x BUT I cannot do that as that is going to break our production environment.

Software information:

{
  "name" : "_BwkrrP",
  "cluster_name" : "<OMITTED>:test-5",
  "cluster_uuid" : "l0h6_<OMITTED>",
  "version" : {
    "number" : "5.6.17",
    "build_hash" : "59bb0dc",
    "build_date" : "2020-01-03T11:28:23.851Z",
    "build_snapshot" : false,
    "lucene_version" : "6.6.1"
  },
  "tagline" : "You Know, for Search"
}

You have a few options.

  1. Run Curator in a Python virtualenv. This will allow it to manage its own dependencies outside of the system defaults.
  2. Run Curator from a different machine or VM
  3. Find the old 5.8.2 RPM or DEB package and install that, as it is standalone and requires no system python to even run.

There are probably other variations that would work, but these are the lowest hanging fruit.

Thank you for your response! I chose to run it in Python virtualenv, and it worked there. Thanks again.
