I recently upgraded to version 2025.1.0.1 and am seeing an odd error with the H3HexagonalIndexer, as follows:

H3HexagonalIndexer (H3IndexerFactory): The clause 'GEOMETRY_HANDLING_Filling_Indexes Replace' within 'FACTORY_DEF {*} H3IndexerFactory FACTORY_NAME { H3HexagonalIndexer } INPUT FEATURE_TYPE Creator_CREATED INDEX_OPERATION { Index } DST_ATTR { _h3index } GEOMETRY_HANDLING { Replace } H3_RESOLUTION { 15 } GEOMETRY_HANDLING_Filling_Indexes { Replace } DST_ATTR_Index { _h3index } OUTPUT { OUTPUT FEATURE_TYPE H3HexagonalIndexer_OUTPUT } OUTPUT { <REJECTED> FEATURE_TYPE H3HexagonalIndexer_<REJECTED> }' is not recognized by the factory 'H3IndexerFactory'

Has anyone else experienced something similar?

    Hi ​@pmcpherson ,

    I was able to reproduce the same error as yours with the attached workspace. In my quick test, the error won't occur in FME 2025.0 and earlier, so I suppose it’s a specific bug in FME 2025.1.

    Hope someone from Safe to take a look into this. > ​@DanAtSafe ?

    Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

    Hi ​@takashi,

    Thanks for the quick reply. I figured it was something related to the latest code base, but good to have confirmation.

    Thanks for posting! This has broken one of our workflows as well. In the meantime, we may be able to use a Tiler as a “good enough” workaround. We are moving to FME Flow 2025.1.1 next week, so if someone has a better workaround before then, it would be much appreciated!

    The H3HexagonalIndexer transformer appears broken in FME 2025.1.1 (Build 25615)

    Hi ​@paul_m. I tried using a 2DGridAccumulator and associated SpatialFilter to replace the H3HexagonIndexer, but I don’t like the results. The latest response on the trouble ticket is that they have fixed the problem in code and are currently conducting QA. They expect a fix to be released in the next week or so. I plan to wait for the H3HexagonIndexer to be fixed.
