How to use the File system Connector, Copy File

[rarroyo1]

I'm trying to copy a file from OFB to my local file share.  I've set up an on-premise gateway and use "File System / Copy File".  I get error messages when flow runs: 

InvalidTemplate. Unable to process template language expressions in action 'Copy_file' inputs at line '1' and column '2689': 'The template language expression 'json(decodeBase64(triggerOutputs().headers['X-MS-APIM-Tokens']))['$connections']['shared_filesystem_1']['connectionId']' cannot be evaluated because property 'shared_filesystem_1' doesn't exist, available properties are 'shared_sharepointonline, shared_onedriveforbusiness'. Please see https://aka.ms/logicexpressions for usage details.'.

Can someone share how they set up the Copy File parameters?

Hi @rarroyo1 

Are you using powerapps to trigger the Flow? (Just by looking at the error statement I am guessing you are). In that case, you must have added an action after adding the flow to a powerapps control. This is a known issue for such cases and the remedy is to remove the flow from the control in powerapps and re-add it over there. 

Hope this Helps!

Hi @rarroyo1 

Alright! Can you post a screenshot of the Flow and the action on which the error is popping? That way we might be able to better identify the issue and assist you with this.

I discovered that Copy File just copies a file with Source and Target on my local file system.  It doesn't download a file from SharePoint on OneDrive to my file system, which is what I wanted to do.

I had added the File System Connector after I had already created the Flow and was testing it by using data from previous runs.  I needed to manually trigger the Flow again and test using the new data for it to work.
