Description

I am working on upgrading a project from SaxonJS 2.0 to 2.2. However, when upgrading this webpack project, I am getting an error regarding the resolution of the stylesheet, which is passed via URI:

[10:32:49 AM] uncaught exception: XError:Failed URI resolution: href=xslt/cvr_v1_json2xml.sef.json base=undefined -- TypeError: k is not a constructor; code:FODC0005

   saxon.transform({
            sourceText: wrappedJson,
            stylesheetLocation: `xslt/${sefFile}`,
            initialTemplate: "start",
            destination: "application"
        }, cb);

I have checked by entering the SEF URL manually, and it resolves (Firefox and Chrome).

I did some testing with Webpack in the course of investigating the global object bug. I would have said that we have tests that cover this case, but perhaps I'm mistaken. We'll take a look as soon as possible. Apologies for the inconvenience.

Sorry for the delay. I was trying to reproduce the bug but I'm not having much luck. The repo you point to contains XML SEF files but not the original stylesheets. Saxon-JS 2.x doesn't support XML SEF files, can you provide the JSON versions or the original stylesheets?

If you can describe a little more precisely how to reproduce the problem, that would also be appreciated. Thanks!

There is a JSON based SEF located at https://github.com/HiltonRoscoe/CDFConverter/blob/saxonjs-upgrade/src/xslt/cvr_v1_json2xml.sef.json. The CVR JSON2XML is configured to use this style sheet.

I've had a look at the GitHub project, but I've not yet worked out how to use webpack to try testing changes myself; so I don't yet have a working repro.

I'd be interested to know what happens if you try updating to use Saxon-JS 2.3 rather than 2.2. I can see that the failure arises internally within the call to resolveUri (in NodePlatform.js); and there were some code changes in this area for the 2.3 release (e.g. re bug #5021).

I'm not necessarily confident that it'll be fixed, but perhaps you'll see a different (more useful) error message...

I've upgraded to SaxonJS 2.5 and get a similar, but slightly different error:
