Hello,
I am encountering a new problem in ETL. So far, my transformations were running and I was quite satisfied. However, after I make some modifications in the .etl file and try to run the transformation again, I start seeing this error message:

An internal error occurred during: "Launching m1tom2".

I tried to create a new project and run the transformation again. For the first 2-3 times it works fine, but after making changes in the etl file a couple of times, this error pops up.

Could someone please take a look at the issue? All these errors are taking a lot of time Sad

Looking forward to some help,
Sincere regards,
Chandrakana.

Hi,

Could you please put together a minimal example [1] we can use to reproduce this?

Cheers,

Hi Dimitris,
Thank you so much for your reply. The problem got solved by restarting Eclipse and cleaning the project a couple of times.

Thank you,
Best regards,
Chandrakana.
