What should I do in the case of Inkspace Failed status?

Failed status means that the Inkspace update hasn’t been completed correctly and your data is not updated. In this case check the added imports. 

Go to the list of imports by selecting the "Imports" tab. See which of the added imports failed. Enter the settings of that import and check the address of the source file you provided – it is possible that it displays an error, preventing us from retrieving the data. If the file is correct, go to the "Mapping" section and check if the file structure is changed. 

Pay special attention to the "ID" field, which is required for mapping imports. Correct the mapping and accept the changes introduced by clicking "Adjust Changes" on the list of imports.
