Dear Sayand,
Good day! Thank you for posting your query in our community.
Based on your description, you encountered when creating a Power Automate flow.
However, I’d explain that, because this problem is related to Microsoft Power Automate, I found threads which has the similar query with you in Microsoft Power Automate Community, such as: Solved: The 'inputs.parameters' of workflow operation 'Cre... - Power Platform Community (microsoft.com), Solved: The 'inputs.parameters' of workflow operation 'Cre... - Power Platform Community (microsoft.com).
So my suggestion is to post on dedicated Microsoft Power Automate Community, the members and engineers in this community are more experienced in this area. You will get a more detailed and professional answer to your problem there.
We appreciate your understanding.
Sincerely,
Jazlyn | Microsoft Community Moderator
