Spatie\CalendarLinks\Link" not found

Hi, steven.vdw -- sorry to bounce you around but it looks like you were on the right track seeking support in the post install forum → . I'm not sure why the first response there pointed you to the issue queue.

The Spatie\CalendarLinks\Link class is provided by a dependency managed by composer -- it's not possible to just put the files in a directory and have it wok. Composer also handles the autoloading of the file so needs to be involved in the installation.

Hopefully you'll get some more helpful responses to your forum post soon.

I've run into the exact same issue....
Error: Class "Spatie\CalendarLinks\Link" not found in Drupal\calendar_link\Twig\CalendarLinkTwigExtension->calendarLink() (line 79 of modules/contrib/calendar_link/src/Twig/CalendarLinkTwigExtension.php).

This worked on my local machine (mac, running php8.1), but does not work on RHEL7 running php8.1. Sure hope someone figures this out... It leads to showing nothing but a WSOD with error message.

@jayvolk what does your deploy process look like? Are you installing composer dependencies on the RHEL7 machine or committing and deployed vendor assets? Or something else?

Just want to establish if this a similar case as the original poster or something else.

Wells... I am using a composer install on the live server. (even tried rm -rf ing the vendor and modules/contrib folders and reinstalling to see if that would help... it didn't.

Hm ok... could you share a list of the steps you took deploying the application? And perhaps an example composer.json file?

And on the non-working deployment can you confirm if you do indeed have the file {root}/vendor/spatie/calendar-links/src/Link.php present?

Yes /vendor/spatie/calendar-links/src/Link.php is present.

and. this is composer.json

I was able to start an instance in Lando using that composer file and generate links without issue.

Could you share the contents of your vendor/composer/autoload_psr4.php from the host?

Sure, but before that does anything within this module "dial out" to the internet? If so, that could be the problem as we're behind a proxy on this server.

Nothing in the module but composer certainly does to get packages. Sound like you have the expected file though. The class that the error message says you are missing is in that file and should be autoloaded and ready to go.

My local version of that file and the remote version are identical.

And it has the expected 'Spatie\\CalendarLinks\\' => array($vendorDir . '/spatie/calendar-links/src') line.

Ok. Can you share your twig template calling one of the module functions and a full backtrace of the error? Tracing twig errors is always a nightmare but maybe we'll get something I can see or reproduce...

{% set link = calendar_link('google', node.title, node.field_start_date, node.field_end_date, '', content.body|render, node.field_talk_title, content.field_room.0|render ~ ' ' ~ content.field_building.0|render) %}

Add event to Google

{% set link = calendar_link('ics', node.title, node.field_start_date, node.field_end_date, '', content.body|render, node.field_talk_title, content.field_room.0|render ~ ' ' ~ content.field_building.0|render) %}
Add event to iCal

I'm not able to reproduce this using the provided configuration and example (in Lando, anyway) but I'll leave this open as needs more info for now in case anyone else has the issue and/or is able to determine what the source is. The only thing I can think is something specific to RHEL but that seems pretty unlikely...

Yes, I suspect that it's related to the proxy server not allowing something in to be downloaded. Thanks for digging tho'

Were you able to add calendar events to outlook?
