Error 4204: Invalid binary vector format

Error Code
SQLSTATE
Error
Description

4204

ER_VECTOR_BINARY_FORMAT_INVALID

Invalid binary vector format. Must use IEEE standard float representation in little-endian format. Use VEC_FromText() to generate it.

Possible Causes and Solutions

Argument is not a Valid Binary Vector

For example, the function expects a binary vector. If not given one, this error will result:

SELECT VEC_ToText(x'aabbcc');
+-----------------------+
| VEC_ToText(x'aabbcc') |
+-----------------------+
| NULL                  |
+-----------------------+
1 row in set, 1 warning (0.000 sec)

Warning (Code 4204): Invalid binary vector format. Must use IEEE standard float 
  representation in little-endian format. Use VEC_FromText() to generate it.

The solution is to provide a valid binary vector:

SELECT VEC_ToText(x'e360d63ebe554f3fcdbc523f4522193f5236083d');
+---------------------------------------------------------+
| VEC_ToText(x'e360d63ebe554f3fcdbc523f4522193f5236083d') |
+---------------------------------------------------------+
| [0.418708,0.809902,0.823193,0.598179,0.033255]          |
