Deploy flow from winter 21: ​​​​​​​ Property 'filterLogic' not valid in version 49.0

Hi...

I've created a flow in a Sandbox with Winter'21. I could not deploy it to production. I got the following error:
 Property 'filterLogic' not valid in version 49.0

HI Guntin,
Can you change the API version of the flow to 50.0 in the metadata file of flow and try to deploy the same? This should  fix the issue for you.

Hope this helps you. Please mark this answer as best so that others facing the same issue will find this information useful. Thank you

Confronted the same error while deploying process builder. Retrieved again with API version 50.0 & deployed successfully. 'FilterLogic' tags weren't present this time.

Hi... my error was that I tried to deploy it through source instead of mdapi. So, if you retrieve and deploy the flow through mdapi everything works. It makes sense...
