[Fatal Error] wedge frontAndBackPlanes centre plane does not align with a coordinate

Good day Foamers,
Thank you for reading my post.

I have a very simple and repeatedly asked question. Sorry I did not find any satisfactory solution yet. I have axisymmetric 2D mesh of a simple bubble enclosed in rectangular domain. I just consider 1/4 portion for reduction. I make the mesh in fluent in 2d plane and save it in ascii format .msh. Afterwards i used https://github.com/krebeljk/wedgePlease utility to make it axisymmetric grid for wedge boundary. Every thing goes successful.

The problem started afterward. When i solve the generated grid for my case (Which is correct), I get the following Error.

--> FOAM FATAL ERROR: (openfoam-2012)
wedge frontAndBackPlanes centre plane does not align with a coordinate plane by 1

From virtual void Foam::wedgePolyPatch::calcGeometry(Foam::PstreamBu ffers&)
in file meshes/polyMesh/polyPatches/constraint/wedge/wedgePolyPatch.C at line 100.

FOAM exiting

As the Error suggested i went back to Ansys and offset the geometry plane by 0.5 mm so that the coordinate plane come exactly at the middle as you can see in the attach file. However the error still persists and i do not know how to get rid of it. Attachment 84736

If anybody senior can recommend me a very simple method to get rid of this problem, I would be extremely indebted to you.

Thank you so much for reading my post.
Regards,
Danny
