Hi,
I need to set an extension property on the return line in both linked return and non-linked return scenarios in POS. I have tried to implement SaveExtensionPropertiesOnCartLinesClientRequest on POS side to save the property but the standard throws the errors in screenshot
Is this an expected behavior? Is there any way to set ext properties on -ve line ? Has anyone tried this before and has been successful ?
I get the same error while saving the attributes as well.
