"No files for wrapper" error

[blacktek]

Hello,
in our development environment we're experiencing some random "No files for wrapper" for the ajax requests
https:///quickdevbar/index/ajax?_=1734367183135 (return a 202 HTTP return code)

After some debug, we've noticed that the problem starts with the execute method in vendor/vpietri/adm-quickdevbar/Controller/Index/Ajax.php

try {
$this->qdbHelperRegister->loadDataFromFile();

        $this->_view->loadLayout('quickdevbar');
        $output = $this->_view->getLayout()->getBlock('quick.dev.maintabs')
            //->setNeedHtmlContent(true)
            ->toHtml();
    } catch (\Exception $e) {
        $output = $e->getMessage();
        $resultRaw->setStatusHeader(
            \Laminas\Http\Response::STATUS_CODE_202,
            \Laminas\Http\AbstractMessage::VERSION_11,
            'QDB Error'
        );
    }

if we use
$this->qdbHelperRegister->loadDataFromFile(true);
it works; the function is defined like this:
public function loadDataFromFile($ajax = false)
{
$wrapperContent = $this->qdbHelper->getWrapperContent($ajax);
$this->setRegisteredData($wrapperContent);
$this->pullDataFromService = false;
}

the stack trace for the error is

@vpietri
this error seems related to frontend FPC (redis FPC too). If we add a random string to the page URL it disappears

[martingg88]

any idea how to sovle this issue?

[vpietri]

Hello @martingg88 @blacktek ,

Do you reproduce this issue on the home page?
After several refresh you still have the same error?

By my side, I can reproduce this error only when I restore a browser session :-(

Hi @vpietri
we decided to change toolbar, unfortunately we can't help anymore. I can't remember now where it was happening, sorry :(
