how to handle dynamic filenames in 'update a row'

(0) ShareShare

Posted on by 1

 

Hello.

 

Another person who is (relatively) new to flows with a need for guidance.

I have a flow that is triggered by a form submission. The flow takes the form responses and adds them to a sharepoint list.  It also creates a new subdirectory in my sharepoint site, and creates a copy of an excel file in that new subdirectory. Both the subdirectory and excel file are named with a field value from the MS Form, so they are dynamic. This all works fine. 

 

What's not working is the "update a row" action that comes next - it doesn't like variable based file names and paths.  I've read some other threads about using SPLIT expression and I've tried it, but I still get save error:

 

Flow save failed with code 'WorkflowOperationParametersExtraParameter' and message 'The API operation does not contain a definition for parameter 'undefined'.'.

 

Any help/guidance would be appreciated. Thanks.

    Hi @mgermony,

     

    What are you input in the split() function?

    If you not similar with split function, you could refer to this doc, it will help you something:

    https://docs.microsoft.com/en-us/azure/logic-apps/workflow-definition-language-functions-reference#split

    If you could share some screenshots of your Flow, it will help us to assist you better, thanks.

    Hi @mgermony 

     

    The excel connector for actions like Create a New Row, Update a Row does not support dynamic file names and table names. This can be done using the Graph API though. https://docs.microsoft.com/en-us/graph/api/table-post-rows?view=graph-rest-1.0&tabs=http 

     

    You can either create a custom connector or use the HTTP action for this one. 

     

    Hope this Helps!

    This is an old post but I will leave this here anyway incase someone else runs into a similar issue. If you add your column names and cell values in JSON object format it works. So it would be entered in like this { "Column1": "Value1", "Column2": "Value2" } and so on. Replace the "Column1" and "Value1" with the name of your column name and cell value. This worked for me, hopefully it works for you. I'll include a screenshot as well for reference.debug1.PNG
