Gulp error

[Zubrik]

I had resolved this problem some time ago: #676

Now when I run my gulp task, I get this error:

Error: (unknown path)
  Error: Cannot use "in" operator to search for "foo" in unexpected types.

So it seems I can't do this anymore:

{% if 'foo' in activePage %}

Yesterday I updated node.js to v4.4.1, I don't know if that could have something to do with the problem.

Thanks.

What type of object is activePage? Can you give a full example for reproduction?

Closing pending further info from OP.

Hi,

activePage is a variable which contains a string ("foo bar"). I want to check if "foo" exists in that string, so I do

{% set activePage = "foo bar" %}
{% if 'foo' in activePage %}
  <p>foo exists</p>
{% endif %}

which returns the error:

gulp-notify: [Error running Nunjucks] Error: (unknown path)
  Error: Cannot use "in" operator to search for "foo" in unexpected types.

The source is clear:

nunjucks/src/lib.js

Line 288 in 3817607

exports.inOperator = function (key, arrOrObj) {

It must be an array or an object.

The source is clear, but it's wrong :/ The in operator should work on strings, and it does in Jinja2. And it used to in nunjucks as well, until I merged what was supposed to be just a simple PR to support objects and provide better error messages, but I totally missed the fact that that PR should still have allowed support for strings. That's my fault, I'll get it fixed. Sorry about that @Zubrik.

Just released v2.4.2 with the fix for this.
