Need help w/recurring error

[Alecia Reyes]

All,

My company is working with a TMS software and we have about 45  users. One user is getting an error when using the software to call out to another website. He is the only one getting this error and it's been happening every time he does this daily since May. We have this issue escalated within the vendor and their lead developer is very engaged but has yet to determine why this is happening. One thing he has narrowed down is that after the user logs in each day, the first time he tries to make this request it works. Also, if later in the day he tries and gets the error, if he opens an additional instance of the software, the first time he makes the request it works. On our end, we have checked all our network lines, servers, de and re-installed his software and even put him on a brand new laptop, nothing helped. I have pasted the error below.

Thanks in advance!!

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of 'java.lang.StringBuffer' (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value ("movement.id")

Usually this would not be enough to figure it out, but I recalled
something... so it is probably this regression:

https://github.com/FasterXML/jackson-databind/issues/3446

so depending on the version of Jackson, it'd be necessary to upgrade
to Jackson 2.13.3.

I am not 100% sure which version the problem started in but I'd guess
either 2.12.0 or 2.13.0: the root cause is due to Jackson
introspection being limited for JDK core types so a single-argument
Constructor of `StringBuffer` was not found and thereby explicit
deserializer is needed.

I hope this helps,
