now, import to elasticsearch also seems failing for the past several days, in that case seemingly over:

`fw-fanctrl` error

Error: Some members of the group 'manual' could not be processed: 
 1: While processing flake git+https://github.com/TamtamHero/fw-fanctrl?ref=packaging/nix

Caused by:
    0: Failed to gather information about git+https://github.com/TamtamHero/fw-fanctrl?ref=packaging/nix
    1: command 'nix flake metadata --json --no-write-lock-file 'git+https://github.com/TamtamHero/fw-fanctrl?ref=packaging/nix'' failed: exit status: 1

that one should be fixed with #1302 (thanks for the merge!), but now it seems to be failing because github:surrealdb/surrealdb may have started using allow-import-from-derivation
