How to get a log

Docker log

If you're running changedetection.io from the docker, it's as simple as calling this command:
docker logs changedetection.io &> logs.txt

Workaround for 'pyinit_main: can't initialize time' error on Raspberry Pi

When using or installing changedetection.io at the Raspberry Pi device, you can experience these errors:

• docker-compose top or docker top changedetection.io do return:
  Error response from daemon: Container {CONTAINER_ID} is restarting, wait until the container is running
• docker logs changedetection.io &> logs.txt produces logs with the following error:
  pyinit_main: can't initialize time

As per https://github.com/linuxserver/docker-papermerge/issues/4, run these commands to workaround this problem: wget http://ftp.us.debian.org/debian/pool/main/libs/libseccomp/libseccomp2_2.5.1-1_armhf.deb sudo dpkg -i libseccomp2_2.5.1-1_armhf.deb

No Notifications

Make sure you're not sending too long messages, as some notification targets do have message length limitations.
For example, too long notification message submitted to the Telegram will produce the following error in the log file:

WARNING:apprise:Failed to send Telegram notification to 196289410: Bad Request: message is too long, error=400.
DEBUG:apprise:Response Details:
b'{"ok":false,"error_code":400,"description":"Bad Request: message is too long"}'

You can easily get out of length limitations is you're including {current_snapshot} into the Notification Body.
