No, it is telling you that the input geometry (the one that you feed
into st_transform) has the SRID -1 which is reserved for unknown SRIDs.
As st_transform() transforms between two reference systems /
projections, you have to use setsrid() to apply the correct srid to the
source geometry, and then you can transform it to the desired targed
