I am getting SharePoint files, then create them inside Blob, but before moving the file i need to check if the file already exists inside the Blob, for this i used the "Get Blob Metadata (v2)", but this action will fail if the file does not exists.. so how i can overcome this?

now i am checking the status code if its equal to 404, the i assume that the file does not exists.. but how i can eliminate this? is there an action to check if blob file exists without the need to handle errors?

here is the flow, where the "Get file content" is configured to run even if the "Get Blob Metadata(v2)" fail:-

Hi @johnjohnPter

You can either use list blobs and filter by the name but you still end up checking if you received something.

or you can simply create a parallel scope (or jus actions), right after the get metadata and on one just set it to run on success and the other on fail/skipped/timedout

Then you won't be checking, but essentially anything you call is going to require you to check if it returned something (such as checking the length of list blobs.

So unless you do the RunAfter check model, which requires no code at all and no conditions, you will have too.

If these suggestions help resolve your issue, Please consider Marking the answer as such and also maybe a like.

Thank you!
