responsive_image_block error

[alter-kaker]

Hi!

I am getting the following error when using responsive_image_block:
~/.rvm/rubies/ruby-2.4.1/lib/ruby/2.4.0/psych.rb:377:in `parse': (<unknown>): mapping values are not allowed in this context

This is my code:

{%- capture path -%} assets/images/_sources/{{ page.featured-image.path | default: site.featured-
image.path }} {%- endcapture -%}
{%- capture alt -%} {{ page.image.alt | default: site.featured-image.path }} {%- endcapture -%}
{% responsive_image_block -%}
  path: {{ path }}
  alt: {{ alt }}
{%- endresponsive_image_block -%}

The responsive_image tag works, but I need to use Liquid variables.
Thank you.

It turns out that the tag works with no leading whitespace at all inside the block. Perhaps this can be made clearer in the documentation?

[wildlyinaccurate]

It should work fine with whitespace, so long as the indentation is consistent (this is mentioned in the docs). There are even tests to make sure this works, although none of the tests use whitespace control like you are in that code ({%- ... -%}).

Was the indentation within that block using tabs or spaces?

[alter-kaker]

The indentation was using spaces.

Hi there, I have the same issue, but how to I fix that?

[grauschnabel]

my problem was different. surrounding {{ path }} and {{ alt }} with '' worked fine. Maybe a sentence will be handled like a list of strings instead of a string?

[wildlyinaccurate]

@grauschnabel the responsive_image_block contents are parsed as YAML, which supports unquoted strings as well as quoted strings:

unquoted: I am an unquoted string
single_quotes: 'This works too'
double_quotes: "And this"

If you don't know the contents of the string beforehand, it's probably better to use quotes just to be safe. It might even be best to escape the contents, e.g.

title: "{{ title | escape }}"
