Record Index warnings

Hell all, 

I am able to read my previously created shp file in Fanout mode, but I get this warnings:

Shapefile Reader: Input dataset XXXshp' contains a Record Index file that is not a sufficient length to be useful and will be ignored. Features can still be read but performance may be impacted.

After reading this shp file I am using AreOnAreaOverlayer and fme stacked there with warnings.

 Number of Inner Boundaries: 1

--------------------------------------

Inner Boundary Number: 0

Geometry Type: IFMEPolygon

Boundary:

Geometry Type: IFMELine

Number of Coordinates: 10 -- Coordinate Dimension: 2

===============================================================ccoordinates

============

AreaOnAreaOverlayer (OverlayFactory):

Overlaying requires a tolerance of at least 2.5078612099758616e-13 for these features, and the input tolerance is 0. Setting the tolerance to 2.5078612099758616e-13

When I changed Tolerance from None into Automatic, another warning appears:

@Geohash: The feature is either too big or located on one of the edge cases. Unable to create a geohash with characters in common. Will create a geohash using the center of the feature.

 

Anyone knows how to solve this issue?

I am using fme 2021.2.2.

Prefered python interpreter FME Python 3.8+

 Below parameters for FeatureReader which I am using.

So the first warning about the index file seems to suggest that it might have somehow got corrupted.

 

The warning about the tolerance can be ignored and so can the other one. They are not really very helpful warnings really. Are you unhappy with the results or just concerned?

Hi

Thanks for your response.

As I mention above "After reading this shp file I am using AreOnAreaOverlayer and fme stacked there with warnings."

Hi @kamilsql 

I have the same problem, and I’m suspecting that it’s to do with the shapefile having zero attributes (other than FID and Shape). Would that be the same for you: did your shapefile have any attributes?

I created my shapefile by drawing  polygon in ArcGIS and then converting it from Graphics to Features.
