Thanks, I'm very happy for someone else to investigate this. 👍

For background:

When I click on one of the error message I get to this code:

dcmjs/src/ValueRepresentation.js

Lines 253 to 271 in f0dc199

static createByTypeString(type) {
var vr = VRinstances[type];
if (vr === undefined) {
if (type == "ox") {
// TODO: determine VR based on context (could be 1 byte pixel data)
// https://github.com/dgobbi/vtk-dicom/issues/38
validationLog.error("Invalid vr type", type, "- using OW");
vr = VRinstances["OW"];
} else if (type == "xs") {
validationLog.error("Invalid vr type", type, "- using US");
vr = VRinstances["US"];
} else {
validationLog.error("Invalid vr type", type, "- using UN");
vr = VRinstances["UN"];
}
}
return vr;
}
}

Which reference this issue thread for background:

dgobbi/vtk-dicom#38

But I don't know why the latest changes would trigger more of those cases. Can you maybe bisect between 0.29.5 and 0.29.11 to see exactly which commit leads to the extra logging?

Ah, yeah that would be my change -- it's a symptom of variable VR types, which I just found out were possible: SmallestImagePixelValue, for example.

What my change introduces is the ability to access values differently than their backing data structure, to allow PN (PersonName) type values to return dicom+json when json stringifying, and formatted strings when writing part10 dcm. As part of that change I obtain the ValueRepresentation class for the VR type and call into a function which can add the required accessors. This actually only happens with PN currently (and may indeed forever stay that way).

The good news is this doesn't affect anything; it's safe to ignore it for the time being. The bad news is the dicom standard is a bit messier than I originally thought. I'll have a look at supressing this accessor step for unknown VRs.
