We're having some significant troubles using EO.pdf (v 16.0.1.0) to create PDF and image files.

We have a collection of objects. We loop through that collection, creating a url and and file path, and then a PDF and image for each.

At this point, in a collection of about 250 objects we're only creating 2 pdf files and no images. We've verified the urls and the file path.

With PDF creation, we get one error consistently (see below). With images, we get two different errors. There seems to be no rhyme or reason for why we get one error over the other (we are only getting one error with each attempt). See below for both errors.

One thing we have found is that if we don't attempt to create images (just comment out that piece of code) all of our PDFs are being generated as expected. The reverse isn't true. If we don't attempt to create PDFs, we still are not able to generate images and the same two errors are encountered.

What can we try next?

Thanks!

The update did get us closer. PDFs are now being generated but images are not - we are seeing one consistent error with the image generation:

Our current project is large and requires too many external dependencies to be able to send you a compilable and runnable version. However, I was able to create a small, self-contained test app that uses the EO objects and fails in the exact same way. I have just sent that to the support email address.

Thanks!

Hi,

We have resolved the first issue you reported. In the test project you sent to us it creates PDF file in a loop. We did not notice the time out error in that app. Is there anyway to make the time out error occurs in that test app?

Thanks!
