Code
T2008 vector-size
A near is handed a value whose size is not the size of the column: an input that is declared as a vector of another size, or a list that is written with another number of entries.
Details
The check reads a plan written with rows and a chain in a run that was read. A vector of the wrong length that code hands to near while the app runs is code.T2105.
The fix
Declare the input with the size of the column: vector({ size: 1536 }). Both sides of a search are made by one model, which gives one size.
