Issue with structData Not Returned in Search Engine Results

[masahiro]

I used Vertex AI App Builder to create the search engine.
For the data store, I have selected unstructured data including metadata.
These metadata include title and id as structData.
I requested results from this search engine using the API. Then, depending on the document, there were cases where only derivedStructData was returned and no structData was returned.
When the relevant document is retrieved, structData appears to have been created.
We are looking for a reason for this occurrence.
