com.fasterxml.jackson.databind.exc.InvalidFormatException

Hi,

I get the following error message when sending a simple mail using the latest library.

Track trace:
com.fasterxml.jackson.databind.exc.InvalidFormatException: Can not deserialize value of type java.util.Date from String "2018-04-13T14:50:37.4008047-04:00": not a valid representation (error: Failed to parse Date value '2018-04-13T14:50:37.4008047-04:00': Can not parse date "2018-04-13T14:50:37.4008047-0400": while it seems to fit format 'yyyy-MM-dd'T'HH:mm:ss.SSSZ', parsing fails (leniency? null))

Any suggestions?

Hi Rob

we noticed users receiving that one from time to time, due older version of Jackson library which handles parsing API responses. Updating library will resolve it.

They fixed it in version 2.9.2. It happens since Jackson does not parse "fractional" timezone correctly. Using up to date library should fix this issue.

Hi Rob,

meanwhile, I investigated this issue bit more. I noticed that on my side, jackson annotations were still using version 2.9.0 . I pushed a very small release which should force them to match 2.9.5 version.

Although this did not affect parsing on my side, (it worked fine before too) I am hoping strict versions for jackson provider and annotation to resolve this issue.
