Solutions

1. Provide a value compatible with the field's column type (e.g. a number for number fields, a valid date for date fields).
2. Check the kernel log for the validation detail and correct the template value.

Example fix

Fix the template so a select field references an existing option and a date field holds an ISO date string.

When it happens

Trigger: A new-item template contains a value that fails validation for the target field's type.

Common situations: Occurs when a new-item template field value fails validation against the field type, for example text in a number field or an unknown select option.
