Opencyto - detector name not found in flow data, but pretty sure it's there

Hi, I've saved a wsp workspace in flowjo X that I'm attempting to import into R using opencyto using this code below.  The files are from a ZE5 analyzer.

flowDataPath <- getwd()
wsfile <- list.files(flowDataPath, pattern="FJ.wsp",full = TRUE)
ws <- openWorkspace(wsfile)
gs <- parseWorkspace(ws, name=1, isNcdf = TRUE)

But I get an error during parseWorkspace:

loading data: E:/17cy1713_TSK_96wellSet/TestFiles/G1.fcs
gating ...
Error in .cpp_gating(gs@pointer, mat, guid, gains, nodeInd, recompute,  : 
  FL03-A not found in flowData!

​If I load in one of these files and check parameter names like this below, I can see that FL03-A is indeed one of the parameters present, also the files in my wd are the same as those used in the flowjo workspace.

Am I making a mistake somewhere, or is there an issue with how opencyto is dealing with either my workspace or ZE5 fcs files?

This typically indicates that gate in xml was referring to the raw dimension name 'FL03-A', which is no longer present in the compensated flow data (flowJo adds prefix after compensation, i.e. <FL03-A> or comp-FL03-A).

So double check your xml workspace and make sure the gates are defined on the correct dimensions.

Thanks, I ended up taking a different path for this project besides using flowWorkspace since it was giving me trouble, but I'll try and find some time to revisit this issue and confirm whether this name mismatch was in fact the issue.

Can the problem be solved? I also get the error during parseWorkspace? Any questions?
