Warming the Create PDF action
The 'Create PDF' action that comes with the PDF Potion Bubble plugin is a server side action. All Bubble plugin server side actions are subject to a 'cold start' issue whenever you run them for the first time in 10-15 minutes (the exact amount of time can vary).
The 'cold start' only occurs the first time your user runs the 'Create PDF' action after a 10-15 minutes time period. If your user if using the Create PDF action for at least the second time within 10-15 minutes, there should not be a 'cold start'.
This 'cold start' means there can be an additional 4-6 second pause at the beginning of the server side action. To avoid this occurring, you can use run the 'Warmup' action that comes with the PDF Potion plugin on page load.
This action sends makes a call to the PDF Potion server which effectively establishes a connection between it and your Bubble app. This means that when your user runs the 'Create PDF' action, they should not be subject to the 'cold start'.
Please note: If your user runs the 'Create PDF' action before the Warmup action has completed (which can take 4-6 seconds if you're running it for the first time in 10-15 mins), they may still be subject to the 'cold start'.
