Good morning everyone,
Yesterday we ran into a very strange issue. I have a web application running .NET Core 2.2 that supports file uploading of JPEGs and PNGs, and the application converts them to PDFs for standardization.
There are a handful of JPEGs and PNGs that are being uploaded that are producing blank PDFs.
I was previously running GroupDocs.Conversion 19.10.0, and upgraded to GroupDocs.Conversion 20.1.0 last night, but still saw no change in behavior.
What’s also very strange is that I downloaded the GroupDocs.Conversion for .NET examples here:
and adjusted the code to convert the exact JPEG and PNG files that I’m having issues with, and it worked when running the example classes.
In my code, my input file is a Stream, coming from Azure Blob Storage, and I refactored the example code to also pull the exact same file from Azure Blob Storage, and again it worked. So it seems to be something very environment specific to my running code.
Has anyone encountered anything like this?
I have tried adding Listeners and Loggers to the Converter, but I don’t see any useful output that shows me that there is an issue.
At this point I feel like I have exhausted my troubleshooting ideas, and I could really use some help here.
Thank you in advance!
