Describe the bug On some rooms I got a warning with understandable description, but with weird values, like this:

[2022-03-04T13:33:16Z WARN  synapse_auto_compressor::manager] The compressor tried to increase the number of rows in !aQCReTFThhdPggxxxx:matrix.org between None and 1255815. Skipping...

Why the first value is "None" instead of some numeric value?

And can you explain in more detail what this warning means and is there any workaround to force compress such rooms?
