tryCPEPatchVersionInUpdateWithVendor =
    vendor: version:
    let
      regex = "([0-9]+\\.[0-9]+)\\.([0-9]+)";
      # we have to call toString here in case version is an attrset with __toString attribute
      versionMatch = builtins.match regex (toString version);
    in
    if versionMatch == null then
      {
        success = false;
        error = "version ${version} doesn't match regex `${regex}`";

        success = true;
        value = {
          inherit vendor;
