Missing Dependencies​

When adding a flow, if you see the message Missing Dependencies it means you have to go to the Plugins and download the missing plugins.

Padding is invalid and cannot be removed.​

If you get this error in a processing node while trying to processing a file

Try turning off configurfation encryption by setting a environmental variable or Node Variable FF_NO_ENCRYPT to 1

Time Zone in Docker​

To set the time zone in docker set the environmental variable TZ to your timezone.

The format is Region/City. E.g. Pacific/Auckland not Auckland/Pacific.

If you enter an invalid/unknown time zone, it will be ignored and the time will be UTC.

See wikipedia for a list of possible time zones.

Plugins Empty or HTTPS Certificate Error​

If you're running FileFlows inside a Docker container and encountering issues, start by executing the following command inside the container:

apt-get update && apt-get install -y ca-certificates

This should resolve the problem in most cases.

However, if the issue persists, you can set the environment variable FF_IGNORE_CERT_ERRORS=1 to bypass certificate errors. Please be aware that this approach is not recommended, as it compromises security by ignoring certificate validation. Use this option only as a last resort.
