I have build a flow for half of a year and it works without any problems. After a sharepointupdate the flow doesn`t work anymore.
I get this errormessage but I doesn`t find the error:
Fehler bei einer Azure Resource Manager-Anforderung: „{"error":{"code":"InvalidTemplate","message":"The template language expression evaluation failed: 'The template language function 'formatdatetime' expects its first parameter to be of type string. The provided value is of type 'Null'. Please see https://aka.ms/logicexpressions#formatdatetime for usage details.'."}}“.
Who has the same problem and what was the solution? Thank you.
I cannot tell you why it has been working for so long, but the error messages says the expression failed because the value you wrote the expression on was null. It could be this is the first time that happened in a year. You can use coalesce to handle situations such as that. You can read about the coalesce expression at Power Automate Coalesce Function Explained.
