Error 2001 - unexpected end o JSON input

[diego]

Good morning, several days ago wazuh has been giving me the following error "unexpected end of json input".The installation of wazuh is on ubuntu 20.04. 

Can anyone help me?

Hi Diego,

Hum, did you do an upgrade?

Which version are you running on each Wazuh component?

Looks like an API error or a Dashboard error. 

Any errors in /var/ossec/logs/api.log ? or ossec.log?

If there is no important information there, maybe this may help:

.- Stop Wazuh dashboard:  systemctl stop wazuh-dashboard

.- Delete file: rm  /usr/share/wazuh-dashboard/data/wazuh/config/wazuh-registry.json

.- Start Wazuh dashboard: systemctl start wazuh-dashboard

Let us know if this helps

Jose.

Hi Jose,

After applying the three commands you mentioned, wazuh has started working again.

Thanks for your help
