Hi Polat,If you are using Run from package option while deploying
the project, the application only has read only permission. But for converting
HTML to PDF, we internally launch the browser process from Binaries folder. Due
to the read only permission, the converter unable to launch the browser
process. The reported issue may occur, we could not convert HTML to PDF with
this configurations. So, can you please try the conversion without run from
package option while deploying the app to azure app service.    https://docs.microsoft.com/en-us/azure/app-service/deploy-run-package#run-the-package

Hello GowthamrajThank you so much for your help I have no options to uncheck "Run from package" ​because I'm using Azure Devops Pipeline with steps (Without yaml)First step is dotnet publish, second and third one are docker build and push.

Hi Polat FIRAT,The reported issue may
occurs, if the docker image is not build properly with the pre-requisites and resource
shortage. Can you please try the conversion by manually build the docker image
from docker file, push the docker image to docker hub/azure container registry
and increase the the storage. Then manually deploy the docker image to Azure
app service with Linux docker and update us the details. WebKit: https://help.syncfusion.com/file-formats/pdf/convert-html-to-pdf/webkit#troubleshooting
Blink: https://help.syncfusion.com/file-formats/pdf/convert-html-to-pdf/blink#troubleshooting
Please follow the below KB
steps to convert html to pdf in Azure App service using the Blink rendering
engine with Linux Docker,     https://www.syncfusion.com/kb/11472/how-to-convert-html-to-pdf-in-azure-app-service-using-the-blink-with-linux-docker
       If possible, kindly push the
docker image to docker hub or share the manual steps to build the docker image,
complete code snippet, stack track details. it will be helpful for us to
analyse and assist you further on this.

Hi Polat,Thank you for sharing the details.On
analyzing the provided details, we need to additionally install the libgbm1 dependency
package to perform HTML to Pdf conversion using the latest blink binaries
Linux. Kindly refer to the below code snippet to install the dependency
packages.

RUN
  apt-get update && apt-get install -yq --no-install-recommends
  libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1

HelloStill not working despite no adjustments. You shared an image when I looked at another ticket with the same problem. Would you mind sharing some basic Azure Pipeline YAML? It appears to be connected to the DotNetPublish step. Because it generates an image on my local drive when I publish using Visual Studio (with pubxml), it works. However, the image produced by Azure Pipeline is not wor.

Hi Polat,On our further validation, we were unable to reproduce the
reported issue on our end. We have tested the simple URL to PDF conversion in Linux
docker using blink and the conversion works properly when deploying the docker
image using the Azure DevOps pipeline on our end. We have build and push the docker
image to docker hub container registry and deployed in Azure WebApp. We have
attached the Azure hosted link, code snippet, pipeline build, and push steps for
your reference,Hosted link: https://dockerpipelinetest.azurewebsites.net/Code Snippet: https://www.syncfusion.com/downloads/support/directtrac/general/ze/CodeSnippet-1731912050Please find the pipeline steps below for build and pushing the
docker images to the docker hub container,
