How to get Image/Asset URL in Matrix? I have got a problem with an asset field in a Matrix in an _entry template.
The Matrix is for a step-by-step feature. Each step has his own image.
So the asset field in my Matrix calls: stepImage.

Now in my _entry template I loop over the step Matrix like:

{% for row in entry.steps %}
    ...
{% endfor %}


In this loop I try to get the asset URL like:

  {% set image = row.stepImage.first() %}
  {% if image %}
      {{image.url}}
  {% endif %}


but it does not work. If i dump it, it returns bool(false).

Do you have any ideas?
I'd suggest giving the Matrix templating docs a once-over.
If steps is the name of your Matrix field, then {% for row in entry.steps %} is going to be looping over each of the Matrix blocks you've defined.
Then you'd want to check for the stepImage asset field in the correct block. i.e.
{% for block in entry.steps %}
    {% if block.type == 'myBlock' %}
         {% set image = block.stepImage.one() %}
       
         {% if image %}
             {{image.url}}
         {% endif %}
    {% endif %}
{% endfor %}
