The message "Base price information has been removed as it is invalid." indicates that values are missing from the base price details.

An example log message looks as follows:

If you open this message and click on "Expand all", you can see the details of the message, including the base price information.

Here is an incorrect example of the base price details from the log message:

OTTO Market always requires the following details for the base price:

Sales amount (salesAmount)

Sales unit (salesUnit)

Base price amount (normAmount)

Base price unit (normUnit)

As shown in the example, only the sales amount and base price amount are provided, and the sales unit and base price unit are missing.

An error here could be that a different unit for "piece" is stored in the variant than is maintained in the catalogue, as there are two units for "piece" in the variant.

You can find this view under Setup > Items > Units > Piece

A simple solution would be to store both units for "piece" in the catalogue.
