Section 4.2.3 says:

oemid-random-json = base64-url-text .size 24

It should say:

oemid-random-json = base64-url-text .size 22

Notes:

16 bytes encoded into base64url, with padding, results in 24 bytes. However, the two padding characters, '==', are removed as per the definition of base64url encoding in https://www.rfc-editor.org/rfc/rfc9711.html#section-2-5.2.1, resulting in 22 bytes.
