[Bug]: Multi-byte characters (Japanese) are corrupted in NosqlClient#updateRow due to improper JSON serialization

[T-Nosaka]

Description

The Issue

When using NosqlClient#updateRow in the TypeScript SDK to insert data containing multi-byte characters (such as Japanese), the data is stored in a corrupted state in the OCI NoSQL Database.

Root Cause

In NosqlClient#updateRow, the bodyContent is serialized using the default common.ObjectSerializer. This results in a JSON string containing raw multi-byte characters. When this string is passed to the underlying HTTP layer, it appears that the Content-Length is calculated based on character count rather than byte length, or the encoding is not handled as UTF-8, leading to data corruption at the API endpoint.

Comparison with Python SDK: The OCI Python SDK handles this correctly because its call_api implementation uses json.dumps(), which by default escapes non-ASCII characters into \uXXXX sequences, ensuring a safe ASCII-only payload.

Steps to Reproduce

Use NosqlClient#updateRow with a payload containing Japanese characters: {"name": "日本語"}.

Check the data in the OCI NoSQL Console.

The string appears as corrupted or broken characters.

Suggested Fix

The issue can be resolved by ensuring the JSON payload is ASCII-safe (Unicode escaped) before transmission, mimicking the behavior of the Python SDK.

1. Add a helper method for Unicode escaping:
   JavaScript

/*
 * JSON UTF8 escape (Python-like json.dumps)
 */
jsonDumps(obj) {
    return JSON.stringify(obj).replace(/[^\x00-\x7f]/g, (char) => {
        return "\\u" + ("000" + char.charCodeAt(0).toString(16)).slice(-4);
    });
}

2. Modify updateRow in oci-nosql/lib/client.js (around line 1871):
   Update the bodyContent assignment within oci_common_1.composeRequest:

• [ Before]

JavaScript
bodyContent: common.ObjectSerializer.serialize(updateRowRequest.updateRowDetails, "UpdateRowDetails", model.UpdateRowDetails.getJsonObj),

• [ After]

JavaScript
bodyContent: this.jsonDumps(updateRowRequest.updateRowDetails),

Environment Information
SDK Version: oci-sdk@2.121.1
