configparser.NoSectionError (Python 3.7)

[alpho]

Hello. When my script is restarting I often times will have these configuration errors.

Importing:

import configparser

Absolute file path (attempt to fix this, didn't help):

thisfolder = os.path.dirname(os.path.abspath(__file__))
test_config_path = os.path.join(thisfolder, '/home/pi/test_configuration.ini')
assert os.path.exists(test_config_path)

Load from that absolute path:

Config = configparser.ConfigParser()
Config.read(test_config_path)

My Read / Write functions:

# Read the Configuration File
def readConfig(section, key):
    Config = loadConfiguration()

    return Config.get(section, key)

# Write to the Configuration File
def writeConfig(section, key, value):
    Config = loadConfiguration()
    Config.set(section, key, str(value))

    with open(raindeck_config_path, "w") as configfile:
        Config.write(configfile)

    return Config

The error I'm receiving

Exception in thread Thread-5:

  File "/usr/lib/python3.7/configparser.py", line 1146, in _unify_values
    raise NoSectionError(section) from None
configparser.NoSectionError: No section: 'Server'

I am using threads throughout this script and the script is killed and restarted at the end.

Thank you

I have searched all over google, tried everything I've found with no success. It seems like the configparser does not like threads. I have to use threads for this project however. Any recommendations?

Sounds like a problem in the .ini file you didn't provide.
