rasql - cannot subtract band from decoded file with multiple bands

[Bang Pham Huu]

This test file has 3 bands and one wants to extract first band:

SELECT encode(decode(<[0:0] 1c>, "GDAL", "{\"filePaths\":[\"/home/rasdaman/rasdaman_community/rasdaman/systemtest/testcases_services/test_all_wcst_import/testdata/3D_Timeseries_Regular/SCALED_M_LSTDA_2015-01.TIFF\"]}").0, "png")

Error:

[ERROR] - 2020-10-30 16:49:03,156, qlparser/qtunaryinduce.cc:784: operand of induce dot operation must be of composite type.
rasdaman error 368: Execution error 368 in line 1, column 219, near token .: Cell base type for induced dot operation must be complex.

It looks like duplicate to #2377 (yes it's a different query but same issue with multiband).
