Server error 500: OutOfMemoryError when navigating the panorama view

When you navigate the panorama view in NavVis IVION, the following error appears:

Network request failed: Server Error (500) Handler dispatch failed; nested exception is java.lang.OutOfMemoryError: Java heap space

Cause: One or more POIs contain embedded images in the description field. NavVis IVION enforces a 40 MB maximum content size limit for POI descriptions. When a POI exceeds this limit, NavVis IVION attempts to download the full content and runs out of memory.

This issue commonly occurs when POIs are imported via JSON, CSV, or the REST API, where embedded images are not automatically extracted and uploaded as separate files.

Note: When you add content to a POI using the POI Editor in NavVis IVION, embedded images are extracted automatically and stored as separate files. This automatic extraction does not apply to POIs imported via JSON, CSV, or the REST API.

Resolution

1. Open the POI that contains embedded images.

2. Remove the embedded images from the description field.

3. Do one of the following:

   • Upload the images directly to the POI using the POI Editor.

   • Host the images externally and add a link to them in the POI description.
     

4. Save the POI and confirm the error no longer appears.
