VueJS - Error compiling template: The value for a v-bind expression cannot be empty. Found in "v-bind:data"

Hi everyone,

I've got a strange error:

[Vue warn]: Error compiling template:

The value for a v-bind expression cannot be empty. Found in "v-bind:data"

1  |  <div id="app">
   |  ^^^^^^^^^^^^^^
2  |          <nav class="navbar navbar-expand-lg navbar-light mb-5">
   |  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
3  |              <div class="container">
   |  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
4  |                  <a class="navbar-brand" href="/">Laravel Forum</a>
   |  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
5  |          
   |  ^^^^^^^^
6  |                  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarContent">
   |  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
7  |                      <span class="navbar-toggler-icon"></span>
   |  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
8  |                  </button>
   |  ^^^^^^^^^^^^^^^^^^^^^^^^^

But in my navbar I don't use Vue, so what's going on here?

I also don't see a line number of the error, and npm run watch ran successful.

What can I do?

Thank you! Jeroen

I found the problem: I was paginating the replies on the PHP end...

Hi @korti_mohammed @adirgapalit,

Here's a detailed explanation of what I did and why it didn't work.

I had a list of posts, coming from my API backend.

For each post, I rendered a Post component with Vue, like this:

<Post v-for="post in posts" :post="post" />

What I didn't know is that I used Post::paginate(), in Laravel.

So instead of an array of posts, what I was expecting, Laravel returned a Paginator object.

That is why I couldn't loop over it and v-bind didn't work.

I hope this explanation has been useful.
