I would comment but I don't have enough reputation.

If you change something in your environment, without changing the code, and you get this Error, then it might be an encoding mismatch.

I had the same issue when switching from a 32 bit machine with 4D Driver v11 to a 64 bit machine with 4D Driver v13. Printing out my resultset revealed that the data was not decoded correctly. Updating to v14 on the 64bit machine solved it.
