trouble getting GetVar() to work for my database plugin

[BenWibking]

I've started to work an OpenPMD database reader plugin that uses the OpenPMD-api.

I've successfully created the meshes and variables. I am able to display the meshes and variable names in VisIt, but I can't actually see my data. VisIt doesn't render a Pseudocolor plot of any of the scalar variables, but does not give an informative error message. I've attached my full logs (run with -debug 5) here: visit_logs.tar.gz

I think something may be amiss with my implementation of GetVar(), but I can't figure out what it is.

My plugin source code is here: https://github.com/BenWibking/openpmd-visit-reader/blob/main/avtopenpmdFileFormat.C

The example dataset I'm using to test it is here: exampleData.tar.gz (open the *.pmd file).

The issue turned out to be that VisIt doesn't like it if there are meshes and variables that have the same name. If I add _mesh to the names of the meshes, then it works as expected.
