Warning: Array to string conversion in [path]/metadata.php on line 618

The first time in each session when I load a page with a gallery, I get this error, once for each image in the gallery.

Warning: Array to string conversion in [path]/metadata.php on line 618

I also these errors at the end of the long list of individual image errors:

Warning: Cannot modify header information - headers already sent by (output started at [path]/metadata.php:618) in [path]/actions.php on line 42

Warning: Cannot modify header information - headers already sent by (output started at [path]/metadata.php:618) in [path]/tpl/typowiki/main.php on line 11

Once the all the images are downloaded, the error message goes away on subsequent visits.

I have the same error

dokuwiki-plugin-gallery/classes/BasicFormatter.php

Lines 56 to 70 in 934fd4d

	$imgdata = [
	'src' => $image->getSrc(),
	'title' => $image->getTitle(),
	'align' => '',
	'width' => $w,
	'height' => $h,
	'cache' => ''
	];
	if ($image->isExternal()) {
	$this->renderer->externallink($link, $imgdata);
	} else {
	$this->renderer->internalmedia(":$link", $imgdata); // prefix with : to ensure absolute src
	}
	}

The plugin passes an array as second argument to $this->renderer->internalmedia() but that function expects multiple strings and numbers instead

As far as i can tell this error only affect the "abstract", whatever that is, but not the render of the page

A workaround is to simply remove ", $imgdata" from line 68 (and maybe also from 66)

I get it on Line 620. Kind of annoying, hope a fix comes through.

having the same issue on line 620, really hoping a fix comes soon

Replacing the line with this works:

$this->renderer->internalmedia(":$link", ...array_values($imgdata));
