Tell setup wizard to use python2.7 on Splunk 8.1.1 ?

[stwong]

Hi all,

We upgraded from Splunk 7.3.5 to 8.1.1.     Most of the app/add-on works except one obsoleted one that supports Python2.7 only.   Got error during setup:

01-05-2021 14:26:55.771 +0800 ERROR ScriptRunner - stderr from '/opt/splunk/bin/python3.7 /opt/splunk/bin/runScript.py setup':  The script at path=/opt/splunk/etc/apps/TA-ms-loganalytics/bin/TA_ms_loganalytics_rh_log_analytics.py has thrown an exception=Traceback (most recent call last):
01-05-2021 14:26:55.771 +0800 ERROR ScriptRunner - stderr from '/opt/splunk/bin/python3.7 /opt/splunk/bin/runScript.py setup':    File "/opt/splunk/etc/apps/TA-ms-loganalytics/bin/ta_ms_loganalytics/splunktaucclib/rest_handler/endpoint/validator.py", line 389

As Splunk 8 includes Python 2.7 runtime and binary, possible to tell Splunk to use Python2.7 when handling this app ?

Thanks a lot.
