JSON String Exporter: Files were not exported. Custom format endpoint is unreachable

[wonkenstein]

Hi, I’m trying to export my string translations out as JSON using the JSON String Exporter.

This was working perfectly fine until about an hour or so ago with the API and doing it manually in the “Download” bundle section

Now it just keeps failing with the following message “JSON String Exporter: Files were not exported. Custom format endpoint is unreachable”

My Project ID is 743737

Hi @wonkenstein

Could you please record a short video showing the steps you take so we can reproduce the issue on our side? Alternatively, you can share a screenshot of the app configuration. If you’re not comfortable sharing it here, feel free to send it to support@crowdin.com.

Hi Olena,

I’ve just tried this morning and it’s working again.

The settings hadn’t been changed from last night so I’m not sure what’s happened.

Below is a screenshot of the unsuccessful API call from last night made with Postman

Will reach out again if this happens again.

Had to post this in another reply as was restricted to one image per reply

We’re facing a recurring issue with the JSON String Exporter app. Exports randomly start failing and the only way to recover is to uninstall and reinstall the app on our project. This manual step keeps happening and is disruptive to our pipeline. We need an official response from Crowdin with a root cause and permanent fix so we can continue using the service reliably.

Temporary workaround (for others until Crowdin responds)

This consistently unblocks us, without changing any project/bundle settings:

1. Go to Apps & Integrations in the project.

2. Uninstall the app “JSON String Exporter.”

3. Install the same app again.

4. Export resources again.

Notes: The problem reappears after some time, forcing us to repeat the uninstall/reinstall cycle

Hi @siteware

To get a permanent fix, the best course of action is to contact our support team directly. We’ll need to access your project logs, which will help them pinpoint the root cause of the issue.

Please send an email to support@crowdin.com and include the following information:

• A link to your Crowdin project

• Any specific error messages you’re seeing in the UI when the export fails

Providing this information will help our team get to the bottom of this issue and find a permanent solution.
