In the class VariationAwareImagingSupport if the local variable "variationName" is null the code simply prints "Supplied variation [null] could not be found. Please update your configuration." It would be helpful to know what property it was trying to use at the time. In the context of support someone can give us the feedback --> "I'm seeing this in my log":

2023-07-03 10:36:11 2023-11-17 17:22:02,650 WARN  ia.templating.imaging.VariationAwareImagingSupport: Supplied variation [null] could not be found. Please update your configuration.

Notes
Currently the code looks like this:

@Override
    public String createLink(Property binaryProperty, String variationName) {
        if (isEnabled() && !ImagingSupport.VARIATION_ORIGINAL.equals(variationName)) {
            if (variations.containsKey(variationName)) {
                return variations.get(variationName).createLink(binaryProperty);
            } else {
                log.warn("Supplied variation [{}] could not be found. Please update your configuration.", variationName);
            }
        }

        return createLink(binaryProperty);
    }

• If the variationName is null or cannot be found then we need to know more information about binaryProperty so we can track it down. Otherwise it ends up being noise in the log file.
