When trying to build a flow yesterday I got a confusing error:
Unable to process template language expressions in action ‘Create_Sprint_Period_in_Sharepoint’ inputs at line ‘1’ and column ‘2778’: ‘The template language expression ‘json(decodeBase64(triggerOutputs().headers[‘X-MS-APIM-Tokens’]))[‘$connections’][‘shared_sharepointonline’][‘connectionId’]’ cannot be evaluated because property ‘shared_sharepointonline’ doesn’t exist, available properties are ‘shared_office365, shared_todoist’. Please see https://aka.ms/logicexpressions for usage details.’.
The reason for this error is that you are test running the flow using data from a prior test from before you added the missing component (in this case sharepoint). You simply need to trigger the flow again med fresh data and it will work
