Marko Taglib: Cannot read property 'replace' of undefined

[hedav85]

Marko Version: 5.14.2

Details

If I render a marko template I got the error below from marko taglib

application.js:630 TypeError: Cannot read property 'replace' of undefined
    at render (/projectPath/node_modules/@lasso/marko-taglib/taglib/slot-tag.js:92:57)

I use require('@marko/compiler/register'); to load marko template and then I require the template via const template = require(templatePath).default;

And then I do res.marko(template, {...} to render and send it to the client.

Your Environment

NodeJS 16.6.1
"@lasso/marko-taglib": "^2.0.3",
"@marko/express": "^1.0.0",
"lasso": "^3.4.0",
"lasso-less": "^4.0.0",
"lasso-marko": "^3.0.1",
"lasso-minify": "1.0.4",
"lasso-minify-css": "1.1.4",
"marko": "^5.14.2",

Is there something missing or I'm doing something wrong?
In Marko 4 it works fine. Could it depent on the change from node-require to @marko/compiler/register?

I am having the same issue. When updating to Marko 5 I get the console warning message:
Using "marko/node-require" has been replaced with "@marko/compiler/register".
So I changed marko/node-require to @marko/compiler/register.
Now I get a warning that says:
Using "marko/compiler" has been deprecated, please upgrade to the "@marko/compiler" module.
Even though I am using @marko/compiler...

After making that change and loading a page I get the error: TypeError: Cannot read property 'replace' of undefined

@JPritchard9518 @hedav85 it turns out that @lasso/marko-taglib is relying on some meta data being attached to the template that is not added via the newer @marko/compiler/register by default.

You can opt into adding that meta data again by using:

require("@marko/compiler/register")({ meta: true })

I do think we should figure out a better way to do this in @lasso/marko-taglib though.

@DylanPiercey with the meta flag it works 👍 So the issue is solved for me.
