[avecch]

Good Morning

I am getting a JSON validation error in the following result:

I have this same discovery rule on other servers and all are working, the only difference I noticed in this case was the underline in the name of some bases. Is that the problem? If it is, how to solve? I can not change the base name ...

My Zabbix is in version: 3.4

thanks a lot for any help.
