500 – Internal Server Error

This error is very common if your source file is too large to process. The typical solution is to increase the "memory_limit" parameter accordingly or split your dataset into multiple MPG projects. 

There is no particular size of the memory_limit that we recommend as it solely depends on your data source file. For instance, if your data source file has only 500 records, even 1MB should be enough. However, if you have 100 columns and 150,000 rows, your memory_limit would need to be 256MB or even 512MB.
