Error "initial_value must be unicode or None, not str" SAM

holper

Hi,

I update my old solar and view the next error monitoring page https whit agent in Linux server:  "initial_value must be unicode or None, not str" 

I resolved this problem execute next steps:

 

1. Change the lines 9 and 158 in the file /opt/SolarWinds/Agent/bin/Plugins/APM/probes/HttpProbe.py

Line 9

Original: from io import StringIO

 Changed: from io import BytesIO

 

 Line 158

Original: f = gzip.GzipFile(fileobj=StringIO(body))

 Changed: f = gzip.GzipFile(fileobj=BytesIO(body))

 

2. Reset Agent

#/etc/init.d/swiagentd restart

Or you try Update Solarwinds to netx version

Version Solarwinds:  SAM: 2019.4.2
