displayName (and other config fields) not included in uploadToFileSearchStore request

[kopher1601]

Environment details

• Programming language: Java
• OS: macOS
• Language runtime version: Java 11+
• Package version: 1.38.0

Steps to reproduce

1. Create an UploadToFileSearchStoreConfig with displayName set:

UploadToFileSearchStoreConfig config = UploadToFileSearchStoreConfig.builder()
  .displayName("my-document")
  .build();

client.fileSearchStores.uploadToFileSearchStore(storeName, file, config);

2. The displayName is silently dropped from the actual API request.

Root Cause

In FileSearchStores.java, the getUploadUrl() method (line 910-915) creates a new UploadToFileSearchStoreConfig with only httpOptions and shouldReturnHttpResponse, discarding the original config's fields:

UploadToFileSearchStoreResumableResponse response =
  privateUploadToFileSearchStore(
      fileSearchStoreName,
      UploadToFileSearchStoreConfig.builder()
          .httpOptions(httpOptions)
          .shouldReturnHttpResponse(true)
          .build());

This also affects customMetadata and chunkingConfig.

Expected Behavior

The original config fields (displayName, customMetadata, chunkingConfig) should be preserved and included in the request to the API.
