Hi xinxilas,
It seems that the operator can't work on List, you might need to modify it. But I couldn't know, what expression you use in M code cause thie problem, so if possible, could you please inform me more details information(such as your sample code and your expected output)? Then I will help you more correctly.
Please do mask sensitive data before uploading.
Thanks for your understanding and support.
Best Regards,
Zoe Zhi
