Hi Mendix community, For my application I'm trying to use a custom font (calibri), I need this font to generate a PDF. I have followed the steps as described here: https://docs.mendix.com/refguide/style#custom-fonts-for-pdf-documents I ended up having: fop.xconf, your custom font and the 6 default fonts should be in your project resources folder. the fop.xconf file should include a reference to your custom font. However, when I generate a PDF with my application the following error occurs in my console: com.mendix.core.CoreException: com.mendix.modules.microflowengine.MicroflowException: Failed to read font file arial.ttf at Product.Temp_Product_PDF (DocumentExport : 'Generate PDF (.pdf) document using template 'Product_Template'') Does anyone have experience with this error and knows how to solve it? Best regards, Timo
