Stage 11th block in blockBlobClient.stageBlock return 400 One of the request inputs is not valid.

Which service(blob, file, queue, table) does this issue concern?

blob

Which version of the SDK was used?

v12.19.1

What problem was encountered?

When I am trying to stageBlock 11th block I am receiving 400 One of the request inputs is not valid.

I observed that this is related to the block id. This is the id I am creating:

String base64BlockId = Base64.getEncoder().encodeToString(String.valueOf(counter).getBytes());

and counter is starting from 0. On 11th I had an error (with number of 10 counting from 0). Based on the documentation I see that all ids should have the same length and each base64BlockId for 0 and 10 has exactly the same length, but before encoding of course the length is bigger for 10 than for 0. And as a result I can commit only less than 11 stages. Can you please point out a problem ?

This is my code snippet:

    String base64BlockId = Base64.getEncoder().encodeToString(String.valueOf(counter).getBytes());
    blockBlobClient.stageBlock(base64BlockId, new ByteArrayInputStream(bytes), bytes.length);

I tried with id pattern like 001 but then I received this error on a first stageBlock call.
