The following article lists the most common error messages for MALL XML feeds and their meanings. Based on this information, fixing bugs in the MALL XML feed will be easier.
Instructions on where to find a list of error messages can be found in our article Inserting MALL XML feeds into the portal, working with intervals and error messages.
When correcting error messages, please follow the rules described in instructions for compiling MALL XML feeds.
The list of errors below is also valid for partners with API connection type. These messages may return in response to your call. Subsequently, it is necessary to modify the structure of the call so that the message is removed.
Important:
Duplicate ID in your feed is not possible. If you enter the same product ID more than once in the feed, the system will load only one of these products, ignoring all others. There is no error message in the log about this fact, so pay attention to the uniqueness of your identifiers. If you have more variants of one product, use the option of creating variant products according to our documentation.
Attention:
The error log does not identify which specific product generates the error, so please always check the settings of the entire feed.
You will find a maximum of 1000 errors in the log. If the log shows this number, it is possible that your feed shows more errors. In this case, the errors must be corrected gradually.
