Transformation error when replacing CSV after the initial tranformation #1309

I encountered an error when I was preparing the cube Tobias_Holzernte_m3_Test_copy.

This error happened multiple times, after trying to replace the csv file in the "CSV Mapping" section.

TransformationError # For the initial mapping I used the csv file mentioned in the error message, which was a trimmed version of the actual csv file I was trying to do the cube of. Holzernte_reduced.csv This file does have the same dimensions as the target csv for integration.

The error persists even when trying to go back to the csv which the mapping has been first done for. Also creating a new cube, with new mapping and a different trimmed file did not change the fact that the same error occurs when trying to transform the target csv file into the cube.

Tobias_Holzernte_m3_Test_version2 with the csv: Holzernte_version1.csv TransformationError2

As of today's afternoon, the issue seems to be resolved for this particular cube. I could replace the csv and the transformation happened as expected. However, for a previous build I tried the same with the same error message as presented in the issue above. Did you fix the problem or is this a coincidence? previous build of the cube

This looks unfortunately more like a problem of the Stardog DB not answering consistently. So it might be related to the amount of queries done a a certain time on Stardog. Lets keep this issue open to see if we can make this more robust in the future.
