Could not extract the HubSpot API catalog.
Could not convert string to integer: 2026-03. Path ‘results[0].versions[0].version’, line 1, position 79. https://api.hubspot.com/public/api/spec/v1/specs
This means that the HubSpot API catalogue does not comply with the specifications provided.
An analyst will look into this and try to find a workaround.
