Merge multiple images with StirlingPDF (solution)

Questions

Describe the problem/error/question

Send a variable number of images to Stirling API as formData and merge them to a single PDF.

What is the error message (if any)?

I somehow had managed to achieve the first part (sending the data), but never managed to convert the response into a working PDF file.

What finally worked, was setting the encoding to “arraybuffer” and encoding the response to base64…

PS: you probably need the environment variable
“NODE_FUNCTION_ALLOW_BUILTIN” to be set to “*” or “form-data”
