It looks like there may be a problem with the standard-content-viewer. Try removing the work/ directory in its entirety from the NiFi installation directory. It will get re-created on startup. If there was a problem initially, hopefully a restart will put things straight.
Sanity check: check that the disk where NiFi is installed didn't reach 100% capacity (or nearly 100% where expanding into that work/ directory may reach 100%). -Mark On Fri, Nov 29, 2024 at 9:40 PM Rimmi Anand <rana...@slb.com.invalid> wrote: > Hello there, > > I am using latest Nifi 2.0.0 https://nifi.apache.org/download/.
