What does this error mean?
When you want to restrict your products to specific countries on Leroy Merlin, you can use the "exclusive-channels" attribute to list multiple marketplace channels. This error occurs because spaces have been added after the commas between the channel codes.
The marketplace's system expects a strict, continuous string of characters. Because of the spaces, it does not recognize the entries as valid channel codes.
How to solve it
To resolve this issue, you must update the values sent in the "exclusive-channels" attribute to remove any spaces between the channels. Follow these steps:
Check the attribute values: Go to the Attributes Mapping step in Lengow (or check your source catalog directly) and review the data provided for the "exclusive-channels" attribute.
Remove the spaces: Ensure your list of channels is separated only by a comma, with absolutely no spaces between them.
✅ Correct format: LMFR,LMIT,BMFR,LMPT,LMES
❌ Incorrect format: LMFR, LMIT, BMFR, LMPT, LMES
Resynchronize your feed: Once the formatting is corrected, perform a manual full push to send the updated and valid data to the marketplace.
