Transformer Compatibility Error Log October 2024

  •   less than a minute  

The RudderStack team has recently completed a major refactoring of the rudder-transformer codebase for sources, resulting in two versions of integrations:

info
The v1 sources provide options to customize the source setup as per your requirements, allowing for a more flexible source behavior.

With the rudder-server release v1.37.0, the v0 API of the source integrations will be deprecated.

This change will cause the rudder-server to be compatible only with rudder-transfomer v1.50.0 and above.

Any transformer version below 1.50.0 cause rudder-server to fail with the below error message:
