powermail PHP Warning: Array to string conversion

PHP Warning: Array to string conversion in /html/typo3-composer/vendor/typo3fluid/fluid/src/Core/ViewHelper/TagBuilder.php line 200

It seems to be connected to the dismantling of the file attributes: Line 200 is "if(trim ..."

        foreach ($attributeValue as $name => $value) {
              $this->addAttribute($attributeName . '-' . $name, $value, $escapeSpecialCharacters);
          }
      } else {
          if (trim((string)$attributeValue) === '' && $this->ignoreEmptyAttributes) {
              return;
          }
          if ($escapeSpecialCharacters) {
              $attributeValue = htmlspecialchars((string)$attributeValue);

at TYPO3Fluid\Fluid\Core\ViewHelper\TagBuilder->addAttribute('value', array('name' => 'IMG_6420.JPG', 'type' => 'image/jpeg', 'error' => 0, 'size' => 5182688, 'tmp_name' => '/tmp/phps3at0y'))

In Production Mode I get: Core: Exception handler (WEB): Uncaught TYPO3 Exception: strtolower(): Argument #1 ($string) must be of type string, null given | TypeError thrown in file /html/typo3-composer/vendor/in2code/powermail/Classes/Domain/Service/UploadService.php in line 134.

But types are set in Constants or TypoScript

PHP 8.3 TYPO3 12.4.3 powermail 12.3.0

only when I use the fileupload field

Hello Mr. Schwemer, I see you got permission from the bosses to fix some issues just before Vatertag. Could this one also get a chance?

THANX

The following change worked for me:

As the template Form/Confirmation.html has been overridden by an own extension since powermail v11, changes have to be make in the section Hiddenfields to run in powermail v12.

The markup for that section has to be replaced with the following. After replacement forms with file uploads do work again.

<f:section name="HiddenFields">
	<f:for each="{mail.answers}" as="answer">
		<f:if condition="{vh:condition.isArray(val:answer.value)}">
			<f:then>
				<f:for each="{answer.value}" as="subvalue" iteration="i">
					<f:form.hidden property="{answer.field.marker}.{i.index}" value="{subvalue}" respectSubmittedDataValue="false"  />
				</f:for>
			</f:then>
			<f:else>
				<f:form.hidden property="{answer.field.marker}" value="{answer.value}" respectSubmittedDataValue="false"  />
			</f:else>
		</f:if>
	</f:for>

	<f:form.hidden name="mail[form]" value="{mail.form.uid}" class="powermail_form_uid" />
</f:section>

Looks like it is working here too! Thanks a lot!

Would not have searched for difficulties with file-upload inside th Confirmation-Template.
