Invalid version even after updating the API version

[bionic]

I have a script that runs every day getting a simple report definition. This script has been running fine for a long time without issues. I recently missed the sunset on v201406 so got a few invalid version messages as you would expect. 

However, I updated the library to v201502 and I am still getting the invalid version message without triggers. Googled it but cannot see a similar instance. I checked to see if there were any update issues but can see nothing. And anyway, the error refers to an invalid version which would suggest that is where the problem is.

Any help appreciated.

Exact message is:

An error has occurred: Report download failed. Underlying errors are 

Type = 'ReportDownloadError.INVALID_VERSION', Trigger = '', FieldPath = ''.

Hello,

Could you send me the clientCustomerId of one of the accounts that is failing?

Are you using one of our client libraries?  

Thanks,
