Setting Img src attribute in Angular produces error - angularjs

Question

<div ng-repeat="file in files" class="record-row">
<div class="colCell fileAttributes">
<div ng-if="!(file.thumbnail === '')" class="collCell-container thumbnail-container">
<img class="" ng-src="{{ file.thumbnail }}" />
</div>
<div class="collCell-container name-container">
<a class="name-container--filename">
<span ng-click="getFile(file.id,file.extension,file.fileName)">{{ file.fileName }}</span>
</a>
<div class="name-container--fileweight">
<span>{{ file.fileSizeByte }}</span>
</div>
</div>
</div>
</div>
Angular Version is 1.3.14. The Code worked fine (functions worked and all outputs) until I added ng-src="{{ file.thumbnail }}".
This gives me the error Unknown provider: urlattrFilterProvider <- urlattrFilter
. Even outputting {{ file.thumbnail }} as text outside of the attribute works fine.
Is this way not correct for setting the src of an image?

Answer 1

Just use src="{{file.thumbnail}}"
instead of ng-src="{{file.thumbnail}}"

Answer 2

Not an actual answer but might be helpful:
the Unknown provider:... error usually shows up when we are injecting something to an angular module the wrong way, eiher a mispelled dependency or a dependency injected in the wrong order.
Make sure the error is coming where you're expecting it from, you can just set a breakpoint on exceptions and confirm this.
