@MattWho Hello So I have a file that contains multiple properties like this : ${filename:find('OD_FUS.*.gz'):ifElse("/isod/brt_fin_fd_OD_FUS_pipe_sep", ${filename:find('OD_NCE.*.gz'):ifElse("/isod/brt_fin_fd_OD_NCE_pipe_sep", ${filename:find('DATA_Liste_Partenaire.*.gz'):ifElse("/baccarat/brt_fin_rn_partenaire","notfind")})})} I developed python script that read this file and assign all this content on attribute attr1 And my flow read multiple files and will check if the file match any pattern from will give him destination in HDFS example: filename=OD_FUS20231010.gz.20231010.csv attr1 will have the value "/isod/brt_fin_fd_OD_FUS_pipe_sep" and if the filename does not exists attr1 will have "notfind" But now when I write the expression to attr1 he taked it as string he didn't execute it like this ${filename:find('OD_FUS.*.gz'):ifElse("/isod/brt_fin_fd_OD_FUS_pipe_sep", ${filename:find('OD_NCE.*.gz'):ifElse("/isod/brt_fin_fd_OD_NCE_pipe_sep", ${filename:find('DATA_Liste_Partenaire.*.gz'):ifElse("/baccarat/brt_fin_rn_partenaire","notfind")})})}
