we have the above automation where the MPN ( manufacturer part number) is combined with an internal code ( always 3 digit)
Example MPN in the file: AAC1234567
We want to replace "AAC" with another code "HFHY";
AAC1234567 --->> HFHY1234567
We tried "replace" and "value_map", but the file is not running, and we do not get any error log either.
Please take a look and help us to make a working code.
