pfalez opened a new issue, #16193:
URL: https://github.com/apache/pulsar/issues/16193
**Describe the bug**
When storing a buffer larger than 130 bytes with Java Functions SDK,
retrieving this buffer with the Rest API give a larger buffer.
Example with a buffer of size 131
Stored buffer: (size: 131)
`0a8001127e0a172e6576656e74732e437573746f6d65724372656174656412630a2432336366666263652d623038342d346631352d616565342d32633064313535613166636312026e311a3700000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000`
Retrieved buffer: (size: 133)

the `0a8` seems common to all message that exceeds 130 bytes
**To Reproduce**
Code in pulsar function:
```java
context.putState(input.getAggregateId(),
ByteBuffer.wrap(message.toByteArray()));
```
Code in client:
```typescript
const response = await http.default.get(
'${this.apiConfig.host}/admin/v3/functions/${params.tenant}/${params.namespace}/${params.name}/state/${params.key}',
);
return Buffer.from(response.data.stringValue, 'utf-8');
```
**Expected behavior**
The two buffer should always equals
**Desktop (please complete the following information):**
- OS: Linux
- Pulsar 2.9.1
**Additional context**
Tested on Standalone and cluster version
