Error: cannot find property "..." for wildcard replacement.

[KonradHoeffner]

How can I fix this? I added it as an ID but it still cannot find it:

 <legend>Competency</legend>
    <div typeof="hito:Competency" resource="Competency-{pid}-{hito:competencyLevel}" id="BirthEvent" external >
        
        <input name="hito:competencyLevel" id="hito:competencyLevel" type="resource" select select-options='{...}' external />

    </div>
