How to convert binary string value from error log?
That error indicates that you are inserting a value in a column that is expected to be unique. The error translates any values in the range 0x20 to 0x7E into their easier-to-read form, and uses an \x prefix for others. So the value you are inserting probably looks like this:

0x9F989E726E068B4E978DB541B56512C92D9CE11A695C


(I got that by keeping any pair of values appearing immediately after an \x, and converting any other values (r, n, N, A, e, -, i, and \) to their ASCII hex values. I assume the \ is a literal, but I would have expected it to be escaped.)
