Salt: 'bool' object is not iterable after minion upgrade

Created on 21 Jul 2017 · 2Comments · Source: saltstack/salt

Description of Issue/Question

We've deployed a new minion that was automatically updated to version
Salt Version:
Salt: 2017.7.0

but some of our masters had older versions.

salt master version
Salt Version:
Salt: 2016.11.5

whenever we execute a state.apply the sls can't be applied, although if we rollback the minion salt agent it works.

Setup

(Please provide relevant configs and/or SLS files (Be sure to remove sensitive info).)

Steps to Reproduce Issue

(Include debug logs if possible and relevant.)

apply a state that works on a previous minion version

Passed invalid arguments to saltutil.sync_modules: 'bool' object is not iterable

    .. versionadded:: 0.10.0

    Sync execution modules from ``salt://_modules`` to the minion

    saltenv
        The fileserver environment from which to sync. To sync from more than
        one environment, pass a comma-separated list.

        If not passed, then all environments configured in the :ref:`top files
        <states-top>` will be checked for execution modules to sync. If no top
        files are found, then the ``base`` environment will be synced.

    refresh : True
        If ``True``, refresh the available execution modules on the minion.
        This refresh will be performed even if no new execution modules are
        synced. Set to ``False`` to prevent this refresh.

    .. important::

        If this function is executed using a :py:func:`module.run
        <salt.states.module.run>` state, the SLS file will not have access to
        newly synced execution modules unless a ``refresh`` argument is
        added to the state, like so:

        .. code-block:: yaml

            load_my_custom_module:
              module.run:
                - name: saltutil.sync_modules
                - refresh: True

        See :ref:`here <reloading-modules>` for a more detailed explanation of
        why this is necessary.

    extmod_whitelist : None
        comma-seperated list of modules to sync

    extmod_blacklist : None
        comma-seperated list of modules to blacklist based on type

    CLI Example:

    .. code-block:: bash

        salt '*' saltutil.sync_modules
        salt '*' saltutil.sync_modules saltenv=dev
        salt '*' saltutil.sync_modules saltenv=base,dev
