@Jatinmaya Choudhury Thanks for raising this question! Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused.
Based on the error message can you, please Try running it by calling it
./azcopy
Can you try to re-generate the New SAS token and try again.
Instead of just azcopy. And make sure your working directory, at the time, is the place where the azcopy executable is. If that doesn't work, please let us know The OS can only find azcopy if it was part of the path. Invoking it with a relative path ./azcopy or absolute path /usr/name/bla/azcopy would be the alternatively way.
If the issue still persists, Can you please share the screenshot of the error message and also the complete code (Hiding the PI data)
Hope this helps!
Kindly let us know if the above helps or you need further assistance on this issue.
