Error on Mobile

When creating a file wither to OneDrive, Sharepoint, Dropbox and FTP, it works perfect in the web and desktop application.  When the app is run on a mobile device (Android) I get the same error, not dependant on the service it is trying to create on.


Unable to process template language expressions in action 'Create_file' inputs at line '1' and column '1550': 'The template language expression 'json(decodeBase64(triggerOutputs().headers['X-MS-APIM-Tokens']))['$connections']['shared_ftp']['connectionId']' cannot be evaluated because property 'shared_ftp' doesn't exist, available properties are ''. Please see for usage details.'.


Substitute ['shared_ftp'] for OneDrive, etc.


Any ideas?

Hi @backerman,


Can you please share the configuration of your flow? Also, in which step will the error occur?

Thank you, I figured it out.  I had to delete the Flow from the screen data source, then re-add the Flow to the control.  It must keep a cache of the first variable confirguration.
