Dynamic expression in 'Send HTTP request to sharepoint' URI link

Question

I am creating an approval flow for sharepoint library that requires

1. access rights control
2. minor/major versioning
3. 4 users approval process
4. Editing of file during the approval process is pending

The only option to publish a major version is to send an HTTP request to sharepoint (check out/check in cannot be ran for different users, builtin sharepoint approval process gets automatically cancelled when editing a file)

I managed to get the HTTP Request running when I specified the filename in URI manually.

Whenever I try to specify the filename via dynamic content (doesn't matter if it is a :

1. composed variable
2. expression
3. expression with concat
4. expression with encodeUriComponent

The variable gets left out from the URI link.

URI expression:

Request input when running the flow, the triggerBody()?['fileName']) is left out and nothing is insterted in it's place, resulting in an error - File not found

Is this possible? Is there any alternative approval process that can handle all 4 points listed at the beginning of this text? Seems like every option is missing atleast one requirement that I need.

Hi @Marek Baranko 

Thank you for posting your question in the Microsoft Q&A forum. 

From your description and screenshots, it looks like the issue you’re working through is mainly about building a Power Automate flow that sends an HTTP request to a SharePoint URI. 

Unfortunately, this forum currently lacks a dedicated tag for Power Platform, you might find more targeted support by posting in the Microsoft Power Platform Community Forum Thread. It’s a great space full of helpful, knowledgeable people who are more than willing to walk you through the steps and share their experience. You’ll likely get clearer guidance and the support you need to make this work.   

I’m sorry we can’t resolve this directly here. Redirecting you ensures you’ll connect with the right support team who can provide the help you need.  
Thank you for your patience and understanding.
