Sumit, Looking at EPSG:26912 on spatial reference, http://spatialreference.org/ref/epsg/26912/ and your longitude coordinates (74-76 East, no less) makes it questionable if 26912 is an appropriate projection. That projection looks valid for western Mexico, and midwestern US/CA. You data looks to be roughly in Asia.
I think that error says that it is not in a valid area of the target projection.
