Strange error message in Renderer

protected function doCallback($callback_type, $callback, array $args) { $callable = $this->callableResolver->getCallableFromDefinition($callback); $message = sprintf('Render %s callbacks must be methods of a class that implements \Drupal\Core\Security\TrustedCallbackInterface or be an anonymous function. The callback was %s. See https://www.drupal.org/node/2966725', $callback_type, '%s'); // Add \Drupal\Core\Render\Element\RenderCallbackInterface as an extra // trusted interface so that: // - All public methods on Render elements are considered trusted. // - Helper classes that contain only callback methods can implement this // instead of TrustedCallbackInterface. return $this->doTrustedCallback($callable, $args, $message, TrustedCallbackInterface::THROW_EXCEPTION, RenderCallbackInterface::class); }

Yes I'm pretty sure that '%s' should be $callback.

It's not $callback, I tried. $callback is an array that even exhausts memory when you print_r() it.

I only got the error by accident, it's from the issue in the OP.

I get it when I use the contrib workflow module on a Drupal 10.2.x, when I view a node of a bundle that has a workflow attached to it, where the workflow history is in an EVA on that node.

The '%s' is definitely wrong, but since the parameters are 'flexible' it's a PITA to create a proper error message. Unless there's somewhere a function to convert a "callback" to something readable.

There may actually be such a thing. I would search around the core code base for similar set ups.

I searched the Drupal core (10.2) for the error message to look for similar code sections. (grep -rn "callbacks must be methods" .)
The are occurences in some DateTime classes.

lib/Drupal/Core/Datetime/Element/Datetime.php
lib/Drupal/Core/Datetime/Element/Datelist.php

There the callback is converted as follows:

Variable::callableToString($callback)

The Variable class is already in use in the Renderer class.
