Running bindiff export does not result in .BinExport file being created

[ddelnano]

Describe the bug
I'm trying to diff an envoy file containing debug symbols against an optimized release image. I initially tried to diff them against each other through the IDA plugin window and received the "Exporting the secondary database failed." error.

After looking into the source a bit, I tried to run the /opt/bindiff/bin/bindiff directly to isolate what the problem is. It appears that the .BinExport files aren't being created by IDA. Please see my reproduction steps below and let me know if I can provide any more helpful context!

To Reproduce

1. Download envoy v1.31.1

docker pull envoyproxy/envoy:v1.31-latest
container_sha=$(docker create envoyproxy/envoy:v1.31-latest)
docker cp ${container_sha}:/usr/local/bin/envoy ./

2. Open binary in IDA and wait for initial analysis to complete
3. Save IDA database file and close IDA
4. Run bindiff export from the command line -- /opt/bindiff/bin/bindiff --export directory/containing/envoy-binary/
5. See that no .BinExport file is created

Expected behavior
That a .BinExport file is created and I'm able to diff a file with debug symbols and the optimized release.

Environment (please complete the following information):

• OS and version: Ubuntu 22 VM
• Locale: US English
• Disassembler and version: IDA Free 8.4
• Bindiff v8 -- installed .deb from release page

Additional context

I noticed that bindiff is running the following ida64 command. I tried running that directly on my machine and used opensnoop to track what files ida64 is writing. Attached below are the commands I ran and the output from opensnoop. The ~/.bindiff/logs/bindiff_idapro.log file also doesn't contain much information.
