Reference Layer Deleted #587
Description
The reference layer file that we uploaded somehow got deleted. The table record, however, is still there.
After investigation, the error was caused in read_metadata during sync default layer.
Because the reference layer was processed during sync default layer, CPLUS API tried to read its metadata and assign NODATA value -9999. The raster that was used for reference layer has dtype int16, which does not support -9999.
What I do is update the dtype to float32 when processing the default layer, save it as new file, then upload it to the layer.
