Hello Yosef, there's a couple different reduction interfaces and the handle you get must match.
It depends a bit on the drive you are using. Carpet only supports the "old style" reduction interface that uses: CCTK_Reduce CCTK_ReductionHandle CCTK_ReduceLocalScalar CCTK_ReductionArrayHandle and: CCTK_ReduceArray CCTK_ReduceLocalArray1D it does not support the new interface CCTK_LocalArrayReductionHandle at all. PUGH supports the new one and (I think) the old one as well. The new one uses: CTK_LocalArrayReductionHandle CCTK_ReduceLocalArrays See https://www.einsteintoolkit.org/referencemanual/ReferenceManual.html#x1-1000A and search for A488. So are you using this with PUGH or Carpet? With Carpet it must fail (not supported at all), with PUGH it should work as long as you sue the correct set of calls ie CCTK_LocalArrayReductionHandle + CCTK_ReduceLocalArrays (for PUGH only).
