Just discovered that site myself and it's awesome.  Also check out 'the 
book' 

 
I am finding it very informative even as a wip.  Welcome to the obsession!  
External Images were always a bit of a conundrum for me as well.

Not sure if this helps but the _canonical_uri field is not a default 
field.  I wonder if you have to add it manually before you run your script, 
otherwise nothing runs after that command which seems to be what you are 
describing.  I kind of doubt it because I would think TW would add it with 
the setfield command but it's worth a look.  Also, did you try to run each 
command separately outside of the script and it worked that way?

Welp, of course, as soon as you ask for help in public, you figure it out 
yourself.

I was reading this, hoping for info on build targets 
-- https://www.didaxy.com/exporting-static-sites-from-tiddlywiki-part-2

and I saw that there they were using commands like:

tiddlywiki --rendertiddlers [!is[system]tag[Live]] 
$:/core/templates/static.tiddler.html static text/plain --rendertiddler 
$:/core/templates/static.template.css static/static.css text/plain

where you throw a bunch of ---commandline --options onto a single 
invocation of the "tiddlywiki" command.

That was the problem, of course, and once I got rid of the multiple 
tiddlywiki commands and combined them all into one it worked!

Oh, I thought maybe I should try this with a build target instead of a 
shell script.

So I looked in the tiddlywiki.com docs for an example of build targets. 
 and couldn't find one.

The build *command* is described here 
-- https://tiddlywiki.com/#BuildCommand  -- but it doesn't talk about how 
to define build targets

It refers you to "tiddlywiki folders" here 
-- https://tiddlywiki.com/#TiddlyWikiFolders "for details of defining build 
targets."  But there are no details about defining build targets there; 
build targets are never mentioned.

Under the heading "tiddlywiki.info  Files"  here -- 
https://tiddlywiki.com/#tiddlywiki.info%20Files  we have the following info:

build - a hashmap of named build targets, each defined by an array of 
command tokens (see BuildCommand)

Of course, Buildcommand doesn't tell you anything about arrays of command 
tokens.

I assume from that description, since I know what JSON is and what hashmaps 
and arrays are, that we're looking for is something like:

{
"themes": [
"tiddlywiki/snowwhite",
"tiddlywiki/vanilla"
],
"build": {
  "externalimages": [

  ]
}
}

where what's in "externalimages" are a list of "command tokens" but 
"command tokens" are not mentioned anywhere else.

The documentation is pretty unhelpful here.
