Hi @powersusers ,
Generally, error code 400 means that a setting in an action of the flow doesn’t function as expected. I am afraid that you may need to edit the flow to correct the failure.
Besides, the Search text works fine when testing it on my side. I guess that the failure caused by too many key words in the Search text field.
Could you try to remove several from them and resubmit flow to see if it will work?
Best regards,
Mabel
