Error when accessing /laravel-filemanager

[nille]

Operating system: Ubuntu 16.04.3 LTS (Running in Homestead v5.0.1)
Laravel version: Laravel Framework 5.5.28
Package version: "~1.8"

Steps to reproduce issue:
Just open http://my.app/laravel-filemanager in browser
(It has been working for quite a while before so this is a new issue. Not sure if it's related to package upgrades or similar.)

Should also note that I can still accesss laravel-filemanager from the standalone buttons I have in my application's forms.

I was about the post the same issue! I tried downgrading to 1.8.3 and 1.8.2, but I'm getting the same error, so I guess it has to be a problem with some dependencies breaking their API?
If anyone has found a solution, please share!

[paulkn]

I'm having the same error.

Try this: replace line 335 of LfmHelpers.php from

return lcfirst(str_singular(request('type'))) === 'image';

to

return lcfirst(str_singular(request('type') ?: '')) === 'image';

---

I saw this line from your backtrace:

Doctrine\\Common\\Inflector\\Inflector::singularize(NULL) #1 

This issue might be cause by an upgrade of Doctrine package.

[alalfakawma]

In lfmhelpers.php line 335 replace the return with this:

return lcfirst(str_singular(request('type') ? request('type') : '')) === 'image';

and in vendor/unisharp/laravel-filemanager/src/views/index.blade.php line 209 replace with this:

acceptedFiles: "{{ lcfirst(str_singular(request('type') ? request('type') : '')) == 'image' ? implode(',', config('lfm.valid_image_mimetypes')) : implode(',', config('lfm.valid_file_mimetypes')) }}",
maxFilesize: ({{ lcfirst(str_singular(request('type') ? request('type') : '')) == 'image' ? config('lfm.max_image_size') : config('lfm.max_file_size') }} / 1000)

Hope this helps, it works in mine.

[nille]

Solution works great. Thanks! LOVE this package.

[kmare]

Works for me as well! thanks!

[paulkn]

A simpler solution that still allows you to run composer update is to add the previous version of inflector to composer.json require:{ "doctrine/inflector": "v1.2"} until this issue has been patched.

[hdouanla]

@paulkn's solution worked for me, I will be waiting for the fix to remove the inflator from composer.

[julihermes]

Any news about it?

[thierrymaasdam]

Bump.

[anhducbkhn]

@alalfakawma it worked for me now. thanks.
In my case, I edited in resources/views/vendor/laravel-filemanager/index.blade.php 💃
