S3: NoSuchFieldError: PASCAL_CASE_TO_CAMEL_CASE

[hohwille]

My expectation would be that AWS S3Client is working.

Actual result:

See FasterXML/jackson-databind#2897

Any workarounds (except downgrading jackson to old and insecure versions)?

[hohwille]

So the problem has been discussed and solved in the linked Jackson issue.
Option to fix the problem are:

• change jackson to 2.15.4
• or update AWS s3 client to 2.23.0+ so e.g. to the currently latest 2.24.9

Hence, I am closing this.
