    Topic: Is there a way to increase the timeout of pdf generation for jspreort deployed as docker image? (Azure web app)


    I see no env variable for it in your blog.

  • I am getting sometimes the following error, it doesn't happen always, note that there's a one image as link (img tag) in the html which may be the culprit (that img has to be dynamic because it's related to branding):

    Error: Error while executing pdf-utils operations. Timeout Error: pdf generation not completed after 30000ms

  • You can use reportTimeout config, set the number of ms there, and pass it to the azure web app as an environment variable.
    This can be done in the azure portal / web app / application settings.

  • another solution was to pass the image as base64 instead of url, it made it faster.

  • @jan_blaha So generally any property in config can be passed as env variable?

  • Yes, check these docs - https://jsreport.net/learn/configuration#configuration-sources

    jsreport merges configuration from config file, environment variables, command line arguments and also directly from the application code in this exact order.
