I also get "IOException encountered while reading from a byte array input stream on Welcome page after the upgrade.

Same issue as here : ([Welcome page-IOException encountered while reading from a byte array input stream](https://community.graylog.org/t/welcome-page-ioexception-encountered-while-reading-from-a-byte-array-input-stream/30834))

Loading last opened items failed with status: FetchError: There was an error fetching a resource: Internal Server Error. Additional information: IOException encountered while reading from a byte array input stream.

Looks like there isn`t an immediate solution provided in that topic but also wondering if anyone knows workaround to fix these issues would be helpful.
