pycharm console error - resolve_var

Hi! Could you please provide us a command to reproduce the problem?

Having the same issue, get the error below when running any command in the console. However, the commands do seem to execute, e.g.

>>>x=1
Traceback (most recent call last):
File "/snap/pycharm-community/76/helpers/pydev/_pydevd_bundle/pydevd_vars.py", line 289, in resolve_compound_var_object_fields
return resolver.get_dictionary(var)
AttributeError: 'NoneType' object has no attribute 'get_dictionary'
>>>print(x+1)

So I was also getting this error, and I couldn't understand why.  So I ended up editing my pydevd_vars.py file in the PyCharm Application.

I changed the function

def resolve_compound_var_object_fields(var, attrs):
    """
    Resolve compound variable by its object and attributes

    :param var: an object of variable
    :param attrs: a sequence of variable's attributes separated by \t (i.e.: obj\tattr1\tattr2)
    :return: a dictionary of variables's fields
    """
    attr_list = attrs.split('\t')

    for k in attr_list:
        type, _typeName, resolver = get_type(var)
        var = resolver.resolve(var, k)

    try:
        type, _typeName, resolver = get_type(var)
        return resolver.get_dictionary(var)
    except:
        traceback.print_exc()

To

def resolve_compound_var_object_fields(var, attrs):
    """
    Resolve compound variable by its object and attributes

    :param var: an object of variable
    :param attrs: a sequence of variable's attributes separated by \t (i.e.: obj\tattr1\tattr2)

    """
    attr_list = attrs.split('\t')

    for k in attr_list:
        type, _typeName, resolver = get_type(var)
        var = resolver.resolve(var, k)

    try:
        type, _typeName, resolver = get_type(var)
        if resolver:
            return resolver.get_dictionary(var)
        else:
            return {}
    except:
        traceback.print_exc()

I don't know if there are any adverse effects of this change, and it will likely be whipped out when I update PyCharm, but the issue seems to be resolved.  I hope this helps someone.
