No module named '_bz2' for STIX2 export

[JoePJisc]

I'm trying to export a MISP event to STIX2 using MISP installed on RHEL7 with MISP-RPM, but thisis failing with the following in exec-errors.log.

Can the required bz2 module be added to the misp-python-virtualenv package?

its the same error as I'm currently seeing for the modules that need disabling in #59

Hi JoeP-oss

I created a new misp-pyton-3.9.13-4.el7 package, the bz2 packge is included there. It should be available in the repository within the next minutes

That has fixed the issue and I can now export as STIX 2.

Thanks
