Hi,

I am getting this error when run my power automate flow - 

 

compose - 

items('Apply_to_each')?[concat('Start of WT Period Planned ', '/', ' Revised Date')]
 
compose_2 - 
addDays('1899-12-30',int(outputs('Compose')),'yyyy-MM-dd')
 
These are date fields. Why is this error happening?

Unable to process template language expressions in action 'Compose_2' inputs at line '0' and column '0': 'The template language function 'int' was invoked with a parameter that is not valid. The value cannot be converted to the target type.'.

    Hi @wonka1234 ,

     

    You would like to add some days to 1899-12-30 right? 

    The addend should be number of days rather than a date. Please tell me specifically what days you would like to add to the 1899-12-30 and how will you get that from above action, so that I may help you to generate a function.

    how can I fix this though? These are date fields in excel going into date fields in sharepoint.

    Hi @wonka1234 ,

     

    According to your error message, the issue happens to int(outputs('Compose')). It means output from Compose is not a valid parameter to convert to integer.

     

    Seems like output from compose should be a string as concat() function could only be applied to strings.

    Refer to this link for its usage:
