Hi Users,

We have a scenario, in which we are uploading recording file on "S3" (AWS) after completion of a call through python script.
We encountered error in uploading recording file on S3 for some calls and for some it worked fine. After debugging the issue we have this scenario:
Currently when the calls hangup after being answered (before we get the below mentioned logs in fs_cli), the script returns us an error (logs attached). But if we get the below mentioned [Debug] logs and call hangup after these, no error occurs and script successfully upload the file to s3.
We have not encountered that issue before.

I will suggest you to use Python 3 and change the code accordingly and try. 

As I was boto3 in other process project to upload recording to S3 and had same random issue. After shifting to Python 3, never had any problem.

[SOLVED]
By switching to FreeSwitch 1.10.7 & then building mod_python3 instead of mod_python resolve the issue. (Please run the "ldconfig" command before configuring FreeSwitch 1.10.7 using "./configure" command while installing from source)
Thank you !!!

Thanks! Uday, for your suggestions.
Actually I also have not faced that issue while I tried to upload a file to S3 through python script locally (outside of freeswitch). I have tested successfully both with python 2.7 & 3.7.
We are using FreeSwitch 1.10.6 & we have tried to build mod_python in a way that it should use python 3 instead of python 2, but not succeed. If someone can guide us regarding that. It might help.
Also Can someone understand the logic I send above regarding the logs for successful upload and without these we receive errors ?
