"File D:\drawing.svg" could not be saved."

[fozzzgate]

System: Windows 10 x64
Inkscape Version: 1.1.1

I installed the latest version of inkscape-svgo and get this error ("File D:\drawing.svg" could not be saved."). I used Process Monitor to capture the command line arguments:

"[Path to custom Inkscape extensions directory]\inkscape-svgo.exe" --options=page_1 --precision=2 --pretty=false --enable=sortAttrs=false --multipass=true --enable=cleanupAttrs=true --enable=cleanupEnableBackground=true --enable=cleanupIDs=false --enable=cleanupNumericValues=true --enable=collapseGroups=true --enable=convertColors=true --enable=convertPathData=true --enable=convertShapeToPath=false --enable=convertStyleToAttrs=false --enable=convertTransform=true --enable=mergePaths=true --enable=minifyStyles=true --enable=moveElemsAttrsToGroup=false --enable=moveGroupAttrsToElems=false --enable=removeViewBox=false --enable=removeDimensions=false --enable=removeUnknownsAndDefaults=true --enable=removeUnusedNS=true --enable=removeUselessDefs=true --enable=removeUselessStrokeAndFill=true --enable=removeRasterImages=false --enable=removeScriptElement=false --enable=removeStyleElement=false --enable=removeTitle=true --enable=removeXMLNS=false --enable=removeXMLProcInst=true --enable=removeMetadata=true --enable=removeNonInheritableGroupAttrs=true --enable=removeComments=true --enable=removeDesc=true --enable=removeDoctype=true --enable=removeEditorsNSData=true --enable=removeEmptyAttrs=true --enable=removeEmptyContainers=true --enable=removeEmptyText=true --enable=removeHiddenElems=true D:\Users\[Username]\AppData\Local\Temp\ink_ext_XXXXXX.svgQRO0L1

When I try to run that command in a cmd window and with a real target file, it returns with no output or errors in the command line window. Target file unchanged.

Looking at the ProcMon capture of inkscape-svgo.exe, it calls Windows Error Reporting, so something definitely went wrong:

C:\Windows\system32\WerFault.exe -u -p 2412 -s 560

Unfortunately, inkscape-svgo.exe is a giant black box, so there is seemingly no way to get error data from it. Is there any way to create an unpackaged version for troubleshooting?

The source is here and you can run with node. All the options are also essentially options for optimize from svgo library, if you want to instrument the library yourself.

For above, you can run

node inspect inkscape-svgo.js --options=page_1 --precision=2 --pretty=false --enable=sortAttrs=false --multipass=true --enable=cleanupAttrs=true --enable=cleanupEnableBackground=true --enable=cleanupIDs=false --enable=cleanupNumericValues=true --enable=collapseGroups=true --enable=convertColors=true --enable=convertPathData=true --enable=convertShapeToPath=false --enable=convertStyleToAttrs=false --enable=convertTransform=true --enable=mergePaths=true --enable=minifyStyles=true --enable=moveElemsAttrsToGroup=false --enable=moveGroupAttrsToElems=false --enable=removeViewBox=false --enable=removeDimensions=false --enable=removeUnknownsAndDefaults=true --enable=removeUnusedNS=true --enable=removeUselessDefs=true --enable=removeUselessStrokeAndFill=true --enable=removeRasterImages=false --enable=removeScriptElement=false --enable=removeStyleElement=false --enable=removeTitle=true --enable=removeXMLNS=false --enable=removeXMLProcInst=true --enable=removeMetadata=true --enable=removeNonInheritableGroupAttrs=true --enable=removeComments=true --enable=removeDesc=true --enable=removeDoctype=true --enable=removeEditorsNSData=true --enable=removeEmptyAttrs=true --enable=removeEmptyContainers=true --enable=removeEmptyText=true --enable=removeHiddenElems=true YOURSVGFILE

and you will get a nice node-debugger.

[konsumer]

what version of node are you using?

Same problem with Inkscape 1.2.1 on Windows 11.

Same here. I'm a rookie, but I took the trouble to check debugging.
