Error occurred in handler for 'renderer:browse-files': TypeError: properties is not iterable

I have checked the following:

• I use the newest version of bruno.
• I've searched existing issues and found nothing related to my issue.

Describe the bug

I'm trying to import a postman collection in an empty Bruno instance. When I click the "Postman collection" button, I get the message "Import Collection failed" before even having been able to choose a file. The logs say:

Error occurred in handler for 'renderer:browse-files': TypeError: properties is not iterable
    at browseFiles (/opt/Bruno/resources/app.asar/src/utils/filesystem.js:253:33)
    at /opt/Bruno/resources/app.asar/src/ipc/collection.js:113:20
    at WebContents.<anonymous> (node:electron/js2c/browser_init:2:87037)
    at WebContents.emit (node:events:518:28)

I'm using the latest nightly build for Linux ARM64 (https://github.com/usebruno/bruno-nightly-builds/releases/download/v1.39.0-2025.2.5/bruno_1.39.0-2025.2.5_aarch64_linux.rpm) on Fedora 40. Same happens with the AppImage build.

The other import buttons (Bruno collection, Insomnia Collection, OpenAPI V3 File) are opening a file picker as expected

Hi @sreelakshmi-bruno. Unfortunately this is still crashing with the same error on bruno_1.39.0-2025.2.6_arm64_linux.AppImage. Not sure what's happening, the code seems straightforward at that line...

I've been able to launch the project on the main branch on my machine and the dialog is showing (I can't reproduce the bug). However I'm not sure how to build the project locally to be able to use it (either AppImage or rpm would work).
With npm run build:electron:linux I get a red error on launch. With npm run build:electron:rpm the script fails because it downloads some x86 things while I'm on aarch64.

Maybe the source of the bug is in the packaging and not in the code?

Hi, this issue was fixed in 1.39 release.

For building from source you can add a .env file to the bruno-app package (packages/bruno-app/.env)
with contents

NEXT_PUBLIC_POSTHOG_API_KEY=foo;

We'll add a .env.example to the code base and have docs for the same to make the process more easier.

I confirm this issue is fixed on my side in 1.39.0. Thank you.
