Create Asset SDK methods fail with HTTP 500

[pulkit-skew]

Environment

• SDK: Fireblocks Java SDK version 12.1.2
• Environment: Sandbox (sandbox-api.fireblocks.io)
• API User Role: Editor (upgraded from initial role)
• Java Version: [Your Java version]

Issue Description

The createVaultAccountAsset() and createVaultAccountAssetAddress() methods consistently fail with HTTP 500 error (code 901 "Unexpected error"), while the same operations succeed when called via direct REST API using curl/Postman/Bruno.
All the other SDK method seems to be working fine.

Example of one of the failures
com.fireblocks.sdk.ApiException: createVaultAccountAsset call failed with: 500 - {"message":"Unexpected error","code":901} x-request-id=[9dc6dce6f64758cc08561d0f1df8bea7]
