Error: bad label format for complex variable

[drzraf]

Trying to output a complex (dict) variable triggers a
Error: bad label format

<table border="0" cellborder="0">
  <tr><td><b>
  <font face="Times New Roman, Bold" point-size="16">foo</font>
  </b></td></tr>
<hr/><tr><td><font face="Times New Roman, Bold" point-size="14">ansible_python_interpreter<br/>ansible_user<br/>os_servers = {'foo': {'bar': 'DE'}}<br/></font></td></tr></table>

I suggest the addition of the following filter:

import re
from ansible.parsing.yaml.objects import AnsibleSequence
def to_string(value, indent = 1):
    o = ''
    if isinstance(value, AnsibleSequence) or isinstance(value, list):
        return "- " + "<br/>- ".join(value) + "<br/>"
    if not isinstance(value, dict):
        return value
    for k, v in value.items():
        o += " " * indent  + f"{k}: {to_string(v, indent + 2)}<br/>"
    return re.sub(r'["{}\(\)|]*', '', o)

# env.filters['to_string'] = to_string
