TypeError: strpos(): Argument #1 ($haystack) must be of type string, Drupal\Core\Url given in strpos() (line 358 of core/lib/Drupal/Component/Utility/UrlHelper)

Please post a stack trace. There isn’t much to go on to solve this bug without that.

This primarily occurs when attempting to access the status reports page. My url is: "http://sunraz-dev.localdomain/admin/reports/status"

The website encountered an unexpected error. Please try again later.

Knowing from where the $uri value comes from will go a way toward solving this. According to the stack trace this is in a template, and it looks like something passed into the |t Twig filter is a Url object instead of a string.

Do you have the capability of doing some debugging?

One way to start would be to put this code above line 358 of core/lib/Drupal/Component/Utility/UrlHelper.php:

      if ($uri instanceof \Drupal\Core\Url) {
        echo $uri->toUriString();
        exit();
      }

That is what I would do to just figure out what is going on.

Based on your suggestion, I did the following; which resulted in a blank page and not backtrace information.

Before:

public static function stripDangerousProtocols($uri) {
$allowed_protocols = array_flip(static::$allowedProtocols);

// Iteratively remove any invalid protocol found.
do {
$before = $uri;
$colonpos = strpos($uri, ':');
if ($colonpos > 0) {
// We found a colon, possibly a protocol. Verify.
$protocol = substr($uri, 0, $colonpos);
// If a colon is preceded by a slash, question mark or hash, it cannot
// possibly be part of the URL scheme. This must be a relative URL, which
// inherits the (safe) protocol of the base document.
if (preg_match('![/?#]!', $protocol)) {
break;
}
// Check if this is a disallowed protocol. Per RFC2616, section 3.2.3
// (URI Comparison) scheme comparison must be case-insensitive.
if (!isset($allowed_protocols[strtolower($protocol)])) {
$uri = substr($uri, $colonpos + 1);
}
}
} while ($before != $uri);

return $uri;
}

After:

public static function stripDangerousProtocols($uri) {
$allowed_protocols = array_flip(static::$allowedProtocols);

if ($uri instanceof \Drupal\Core\Url) {
echo $uri->toUriString();
exit();
}

// Iteratively remove any invalid protocol found.
do {
$before = $uri;
$colonpos = strpos($uri, ':');
if ($colonpos > 0) {
// We found a colon, possibly a protocol. Verify.
$protocol = substr($uri, 0, $colonpos);
// If a colon is preceded by a slash, question mark or hash, it cannot
// possibly be part of the URL scheme. This must be a relative URL, which
// inherits the (safe) protocol of the base document.
if (preg_match('![/?#]!', $protocol)) {
break;
}
// Check if this is a disallowed protocol. Per RFC2616, section 3.2.3
// (URI Comparison) scheme comparison must be case-insensitive.
if (!isset($allowed_protocols[strtolower($protocol)])) {
$uri = substr($uri, $colonpos + 1);
}
}
} while ($before != $uri);

return $uri;
}

It would have printed a URL.

Do you have the capability of running a debugger? That is the only way forward unless you can list out steps to reproduce.

I do have the ability to run debugger. However, it appears that debug output is only generated in the browser. After enabling the debugger, all pages are displaying debug output, with the exception of "http://sunraz-dev.localdomain/admin/reports/status". This is the only page that is completely blank, not even an error message, all other pages render perfectly, both other admin and frontend pages. If there is a method to output debug in a text or log file, please direct me to the information.

Which PHP debugger are you using and where did you set breakpoints?

What I surmised in comment #6 is correct. And now you know it is in the status-report-grouped template. Examine it. Also try var_dump($uri) instead of echo as a variation of my suggestion in #6.

Found The Problem

Following days of frustration with trying to identify the root cause of issue that was preventing the rendering of the status page, I was hoping the find a quick and straight forward solution. The answer circled back to the fundamental task of isolating a module that may be the cause. I discovered that the problem was caused by the Translation Management Module Translation Message entity type. Once those were removed, the status page rendered. Problem solved.

I am glad you isolated the problem. Thank you for following up.
