Jeremy,
Following up on this, I believe I have imported the module without issue
(verified by checking the index.js output of ``--build lambda`` ).
However, testing the Lambda in AWS still throws an error.
It seems the issue is that my javascript macro that makes the AJAX call is
actually just using the built-in httprequest capability within TW5. As
such, the AWS console is telling me the variable is undefined in a bunch of
tiddlers (tiddlers listed at the bottom of this message).
So, forgive me if this is a bit of a newbie question, but *how would I go
about making the variable definition global *so that TW itself has a
definition for this type of request?
AWS error with tiddlers using httprequest (note $:/sandbox/myjax_json.js is
my javascript macro... it works well in the browser):
{
"errorType": "ReferenceError",
"errorMessage": "XMLHttpRequest is not defined",
"trace": [
"ReferenceError: XMLHttpRequest is not defined",
" at Object.exports.httpRequest
($:/core/modules/utils/dom/http.js:27:13)",
