Getting error while refreshing Dataflow Gen2

Hi Suraj_1331 ,

The error message indicates an issue with the application of an operator to incompatible types (Number and Record), which suggests there might be a problem in the way certain expressions or transformations are defined within your dataflow.

Please check the steps:

Examine the transformations applied in your dataflow, especially focusing on any expressions that use the operator . This operator is typically used for string concatenation or bitwise operations, so ensure it's being used correctly in the context of your data types

Ensure that the data types of the columns involved in the transformations are compatible with the operations being performed.

Solved: Re: Couldn't refresh the entity because of an issu... - Microsoft Fabric Community

What i do now is after updating Dataflow Gen2,

- i don't click click the Publish button right away,

- I click other tables first,

- close the Dataflow Gen2 to see the workspace again

- find the updated Dataflow Gen2

- wait for few minutes(1-5) because MS Fabric is slow in everything, i dont know if this is because im using Free Trial

- after waiting for few minutes, near the name of my dataflow gen 2 iclick the "Refresh now" button, the one that looks like circle
