To Reproduce
This is on a rather long script and I can;t work out where it is that this is happening. The script will run for a month or two and then ^ .....

I thought I'd drop this here, so it has been reported and dig into it soonish to report more.

I think it may be a bad database entry ( the script pulls file locations and other info from a database ) which is causing this, but am not sure

Version details

• OS: [e.g. Debian, OSX] Ubuntu 20.04.5
• Version [e.g. 1.3.4] 2.1.3

Install method

Quick note, this seems to be related to interpolation: the error is raised here.

Thanks for reporting. This should be fixed in main and in the upcoming rolling release!
