<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>The <code>entity_field_value_definitions</code> tool fails when retrieving field definitions for certain entity types—specifically media and comment—even when a valid bundle is provided.<br>
For example, when executing the tool with:<br>
<code>entity_type_id: media</code> and <code>bundle: image</code></p>
<p>the tool returns an error:<br>
<code>Tool Plugin executed unsuccessfully: Error retrieving field definitions: Missing bundle for entity type media</code></p>
<p>This occurs even though the bundle exists and is valid. The issue appears to be in how the tool creates a stub entity to get default field values:</p>
<pre><span style="color: #000000"><span style="color: #0000BB"><?php<br></span><span style="color: #FF8000">// Stub version of entity to get default field values.<br></span><span style="color: #0000BB">$entity </span><span style="color: #007700">= </span><span style="color: #0000BB">$this</span><span style="color: #007700">-></span><span style="color: #0000BB">entityTypeManager</span><span style="color: #007700">-></span><span style="color: #0000BB">getStorage</span><span style="color: #007700">(</span><span style="color: #0000BB">$entity_type_id</span><span style="color: #007700">)-></span><span style="color: #0000BB">create</span><span style="color: #007700">([</span><span style="color: #DD0000">'type' </span><span style="color: #007700">=> </span><span style="color: #0000BB">$bundle</span><span style="color: #007700">]);<br></span><span style="color: #0000BB">?></span></span></pre><p>
Media entities use bundle as the property name for their bundle, not type. Different entity types use different property names for their bundle key, and hardcoding 'type' causes failures for entity types that use a different bundle key.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<p>Install <code>Tool API</code> module with <code>tool_content</code> submodule<br>
Test <code>entity_field_value_definitions</code> tool using tools explorer<br>
Execute the tool with parameters:</p>
<ol>
<li>entity_type_id: media</li>
<li>bundle: image</li>
</ol>
<p>Observe the error: "Missing bundle for entity type media"<br>
Note: The tool works correctly for nodes and taxonomy terms but fails for media & comment entities</p>
<h3 id="summary-proposed-resolution">Proposed resolution</h3>
<p>Use the entity type's bundle key dynamically instead of hardcoding <code>'type'</code>:<br>
