Description

Hi there,
I build up a test env along this guide https://medium.com/the-sensiolabs-tech-blog/how-to-generate-a-pdf-file-in-a-few-lines-of-code-with-symfony-39786a679d29 . I get allways a corrupt PDF. If I use a blank template file the creation works. You find the corrupt file attached.

Gotenberg Version

8.15.3

Gotenberg Bundle Version

0.3.0

Hi @nhet !

I opened your file with a text editor and saw some HTML at the end.

<!-- Warning: Undefined array key &quot;192.168.0.152&quot; (500 Internal Server Error) -->

Can you give us the corresponding logs ?

[nhet]

Ok,
the only log entry I have found inside symfony is:

[Wed Jan 22 13:25:39 2025] [critical] Uncaught PHP Exception ErrorException: "Warning: Undefined array key "192.168.0.152"" at NativeResponse.php line 82
The NativeResponse.php file is located in ./vendor/symfony/http-client/Response/

And the only place in the code where the IP is stored is the GOTENBERG_DSN configuration

###> sensiolabs/gotenberg-bundle ###
GOTENBERG_DSN=http://192.168.0.152:8890
###< sensiolabs/gotenberg-bundle ###

Can you share us your configuration (config/packages/gotenberg.yaml or config/packages/framework.yaml) to check if the client is correctly configured ? Like in https://github.com/StevenRenaux/GotenbergBundle-Article/blob/main/config/packages/gotenberg.yaml

config/packages/gotenberg.yaml:

framework:
    http_client:
        scoped_clients:
            gotenberg.client:

Some problem with the default gotenberg.yaml from your link / repro

[Jean-Beru]

I reproduced this bug by editing Symfony\Component\HttpClient\HttpClient::create to force returning a NativeHttpClient. I need to investigate more to check if this bug is due to the NativeHttpClient.

FYI, the Symfony HttpClient chooses the best client to use depending on your machine. It prefers AmpHttpClient or CurlHttpClient over NativeHttpClient. So, you can install the curl extension to quickly solve your problem.

[nhet]

Wow, with curl extension the problem seems to be solved. thx @Jean-Beru

[Neirda24]

Great to know it fixed it. @nhet : could you provide us the result of

$ composer show symfony/http-client

please ?

[nhet]

Find the information attached.

httpClient.Info.txt

After a quick look, It could be linked to an empty content length header (really not sure)
