Geo-Zone API returning 'ERROR: Predicated failed'

Hello Dlubal Support Team,

We are currently using the Geo-Zone web service endpoint, to obtain wind and snow load zones for AS/NZS standards.

Our integration worked correctly until 7 March 2026, but since 10 March 2026 all map queries fail with the following error:

ERROR: Predicated failed

Example request (credentials masked):

https://external-crm.dlubal.com/loadzones/data.aspx?map=wind-as-1170-2:2021&position=-37.8152065,144.963937&language=en&login=XXXXX&hash=XXXXX

We also tested:

  • place= queries
  • position= queries

Both return the same error.

However, the endpoint itself appears to be reachable because the following request works and returns the available request count:

https://external-crm.dlubal.com/loadzones/data.aspx?availablerequests=1&login=XXXXX&hash=XXXXX

Additionally, when testing through the API/browser evaluation flow, the underlying error reported is:

ERROR: Evaluation failed: TypeError: Cannot read properties of undefined (reading 'getPosition') at pointMarker_getPosition_lat () at puppeteer_evaluation_script:1:82

This suggests there may be an issue in the Geo-Zone backend evaluation logic.

Could you please confirm:

  1. Whether there was a recent change to the Geo-Zone service around 7–9 March 2026.
  2. Whether the loadzones/data.aspx endpoint is still supported.
  3. If there is a new endpoint or API we should migrate to for Geo-Zone queries.

Thank you for your assistance.

Kind regards,
Meha Jain
