Internal server error, Can't accesses files

peglegtv · January 23, 2025, 12:20am

Issue: when trying to accesses files on my account (admin) I get an Internal server error. it only happens when selecting files. I tested another account and that account works fine.

Internal Server error:

formatted log entry:

[index] Error: Object of class OC\Files\Node\File could not be converted to string in file '/var/www/html/lib/private/Files/Template/TemplateManager.php' line 182
   GET /index.php/apps/files/

Hi @peglegtv,

… but that is not the Request ID from the Internal Server Error Message.

So please post the output of

jq -r 'select(.reqId == "q7ZivWSDK9DxO3vU7t8q")' /path/to/nextcloud.log

@ernolf thanks for the reply.

sorry the image and log didn’t match, I grabbed the screen shot as an example of the messages I was getting.

Hi @peglegtv,

as you mentioned, it is the same error:

Since the error only occurs with that one account, I can only imagine either an error in your file structure, or a broken or incorrectly named file, i.e. with unusual characters or encoding.

Did you already run this command:

docker exec --user www-data CONTAINER_ID php occ files:repair-tree --dry-run

and did you already run files:scan with --verbose? Sometimes that gives valuable clues:

docker exec --user www-data CONTAINER_ID php occ files:scan --verbose -- peglegtv

But as you can see, I’m also groping in the dark.

Much and good luck,
ernolf

peglegtv · January 23, 2025, 4:28pm

Thanks for the reply, I ran those two commands

1st command

docker exec --user www-data Nextcloud php occ files:repair-tree --dry-run

output:

Found 0 file entries with an invalid path

2nd command

docker exec --user www-data Nextcloud php occ files:scan --verbose -- peglegtv

output

+---------+-------+-----+---------+---------+--------+--------------+
| Folders | Files | New | Updated | Removed | Errors | Elapsed time |
+---------+-------+-----+---------+---------+--------+--------------+
| 1101    | 6859  | 0   | 0       | 0       | 0      | 00:00:07     |
+---------+-------+-----+---------+---------+--------+--------------+

still seeing the same error, your not the only one in the dark on this, I’m a windows guy so I’m definitely in the dark

Looks like a regression we accidentally introduced in v30.0.5 and immediately fixed.

github.com/nextcloud/server

[Bug]: Exception in TemplateManager.php after Nextcloud 30.0.5: `Object of class OC\Files\Node\File could not be converted to string`

### ⚠️ This issue respects the following points: ⚠️ - [x] This is a **bug**, no…t a question or a configuration/webserver/proxy issue. - [x] This issue is **not** already reported on [Github](https://github.com/nextcloud/server/issues?q=is%3Aopen+is%3Aissue+label%3Abug) OR [Nextcloud Community Forum](https://help.nextcloud.com/) _(I've searched it)_. - [x] Nextcloud Server **is** up to date. See [Maintenance and Release Schedule](https://github.com/nextcloud/server/wiki/Maintenance-and-Release-Schedule) for supported versions. - [x] I agree to follow Nextcloud's [Code of Conduct](https://nextcloud.com/contribute/code-of-conduct/). ### Bug description The user account does **not** have a `templates` folder in its data directory. --- After updating to **Nextcloud 30.0.5**, the Files app stopped working and displayed an **"Internal Server Error"** when trying to access files. The following exception appeared in the logs: ```plaintext Object of class OC\Files\Node\File could not be converted to string in file '/var/www/html/lib/private/Files/Template/TemplateManager.php' line 182 ``` #### Relevant Code: The issue originates in the `getTemplateFolder()` method in `/lib/private/Files/Template/TemplateManager.php`. The problematic line is: ```php $this->logger->warning('Template folder ' . $path . ' not found or invalid', ['app' => 'files_templates']); ``` #### Cause: The variable `$path` is not a string but an object of type `OC\Files\Node\File`. PHP cannot directly convert such objects to strings unless a `__toString()` method is defined, which triggers the exception. ### Workaround: Commenting out the problematic logging line resolved the issue temporarily: ```php //$this->logger->warning('Template folder ' . $path . ' not found or invalid', ['app' => 'files_templates']); ``` ### Steps to reproduce 1. Update Nextcloud to 30.0.5. 2. Ensure that the user account does **not** have a `templates` folder in its data directory (e.g., `/data/<username>/templates`). 3. Access the Files app through the web interface. 4. An "Internal Server Error" page is displayed. ### Expected behavior The Files app should function without error, even if the template path is invalid or missing. ### Nextcloud Server version 30 ### Operating system Debian/Ubuntu ### PHP engine version PHP 8.2 ### Web server Nginx ### Database engine version MySQL ### Is this bug present after an update or on a fresh install? Fresh Nextcloud Server install ### Are you using the Nextcloud Server Encryption module? Encryption is Disabled ### What user-backends are you using? - [x] Default user-backend _(database)_ - [ ] LDAP/ Active Directory - [ ] SSO - SAML - [ ] Other ### Configuration report ```json ``` ### List of activated Apps ```shell ``` ### Nextcloud Signing status ```shell ``` ### Nextcloud Logs ```json ``` ### Additional info _No response_

You can manually apply the tiny adjustment from here if you don’t want to wait for 30.0.6.

Hi, I’m facing the same issue (exact same error messages).
I’ve also tried the above-mentioned steps, unfortunately, without success. Fortunately, I am still able to sync my files, I’m not sure whether you are able to do so, too.
The only issue is displaying them in the browser web view

peglegtv · January 23, 2025, 8:07pm

@jtr Thanks for the information, Ill have to look into it tomorrow when I have a little more time.

@ren0x my files are syncing too, just can’t view them in the browser. so it sounds like the bug @jtr shared

ren0x · January 24, 2025, 8:24am

Thanks, this works as expected. I deleted the mentioned line in lib/private/Files/Template/TemplateManager.php in the docker container itself (I’m just waiting for the new version), and restarted nginx in the docker container.
I hope I don’t have to recreate it until the update
Issue resolved.
