"failed to export pdf" InDesign

Thanks, Bob!
I figured there might be some better forum for directly reaching Adobe. Any idea how responsive they are to requests there? I suspect when I check it out, I'm going to find a spit-ton of opinions and feature-requests.

I appreciate your quick response, Derek. As I said, this was more of a plea to Adobe to include already-available data in InDesign's error reporting (at least as regards the decade-old "failed to export pdf" error). I'm familiar with how to painstakingly troubleshoot the problem: a series of incremental exports while isolating the problem element. This might seem practical when the document in question in a page or two. But for long-format projects? There's just literally no reason I can imagine that InDesign can't report the actual error it encountered while exporting a PDF.

For my latest encounter with this error, I was thankfully only exporting a relatively small flyer. Took me about 10 minutes to isolate a couple of PNGs as the problem. My question is: Is there some reason InDesign couldn't have either...

1. told me there is a PNG on page 2 causing a problem;
2. told me the precise nature of the problem with those PNGs?

The pre-flight error reporting does this (although, pre-flight's green dot indicated there were no errors in this case), so why shouldn't the export error reporting do the same? Again, the data is available. I'd appreciate if InDesign would share it with the end-user. Again, yesterday's was an easy fix. Larger projects, I've blown 30 minutes of productivity chasing down a mysterious error.

I'll post this in the User Voice forum and keep my fingers crossed!
