Error: Object of class __PHP_Incomplete_Class could not be converted to string

Hey @adrian I'm getting an error when having a Nette ArrayHash in a session variable:

Error: Object of class __PHP_Incomplete_Class could not be converted to string in /var/www/html/site/assets/cache/FileCompiler/site/modules/TracyDebugger/panels/RequestInfoPanel.php:813
Stack trace:
#0 /var/www/html/site/assets/cache/FileCompiler/site/modules/TracyDebugger/tracy-2.10.x/src/Tracy/Bar/Bar.php(143): RequestInfoPanel->getPanel()

#6 {main}

This fixes it for me:

                try {
                    if (is_object($value)) $value = (string)$value;
                } catch (\Throwable $th) {
                    try {
                        $value = json_encode($value);
                    } catch (\Throwable $th) {
                        $value = $th->getMessage();
                    }
                }

Hey @bernhard - Is this how you have the complete block looking such that your new logic is only applied to objects, but when they are an array the behaviour isn't changed?

BTW, this bit of code is a copy of PW's debug.inc file so you should let Ryan know about the needed change there as well.

                if(is_object($value)) {
                    try {
                        if (is_object($value)) $value = (string)$value;
                    } catch (\Throwable $th) {
                        try {
                            $value = json_encode($value);
                        } catch (\Throwable $th) {
                            $value = $th->getMessage();
                        }
                    }
                }
                if(is_array($value)) $value = print_r($value, true);

Hey @adrian this is the whole block:

        // Session
        if (in_array('session', $panelSections)) {
            $session_oc = 0;
            $session = $this->sectionHeader(array('Key', 'Value'));
            foreach ($this->wire('session') as $key => $value) {
                if (
                    $key == 'tracyDumpItemsAjax' ||
                    $key == 'tracyDumpsRecorderItems' ||
                    $key == 'tracyEventItems' ||
                    $key == 'tracyMailItems' ||
                    $key == 'tracyIncludedFiles' ||
                    $key == 'tracyPostData' ||
                    $key == 'tracyGetData' ||
                    $key == 'tracyWhitelistData' ||
                    $key == 'tracyLoginUrl'
                ) continue;
                $session_oc++;
                try {
                    if (is_object($value)) $value = (string)$value;
                } catch (\Throwable $th) {
                    try {
                        $value = json_encode($value);
                    } catch (\Throwable $th) {
                        $value = $th->getMessage();
                    }
                }
                if (is_array($value)) $value = print_r($value, true);
                $session .= "<tr><td>" . $this->wire('sanitizer')->entities($key) . "</td><td><pre>" . $this->wire('sanitizer')->entities($value) . "</pre></td></tr>";
            }
            $session .= $sectionEnd;
        }

Not sure about this and when that code is used.

But I think we can ignore this request. I've changed my code to save values as plain array in the session. The session is not meant to store any type of object, so it's ok if it breaks I guess?!
