Validation Error: Required Element Missing in Request
The error SOAP-ENV:Client.validationError: Validation error occurred. Required element 'Position_ID' is missing from the request
What it means
The request is missing an element that this WWS version treats as mandatory. This often appears after a version upgrade - something that was optional before is now required, or the payload was built against a different version's schema.
Troubleshooting
- Note the WWS version in your request and pull the XSD or docs for that exact version.
- Compare your payload against the schema - required elements change between versions.
- If the integration recently changed WWS versions, diff the old and new schemas for this operation.
- Watch for conditional requirements - some elements are only required when a sibling element is present.
⚡ Quick fix
Add the missing element with a valid value and re-run.
✓ Permanent fix
Pin and document the WWS version per integration. Validate outbound payloads against the versioned schema in your build pipeline and treat WWS version upgrades as a tested change with a schema diff review.
