Populating a word template - ERROR: Failed to retrieve dynamic inputs. Error details: 'e.toLowerCase is not a function'

(0) ShareShare
ReportReport
Posted on by

I have built a flow, triggered when a form is submitted. It then reads data from an excel table. I want it to take data from the table and form to populate into a word template.

I have tried the flow WITHOUT the word template, and just using the dynamic data to send an email, and it all works fine.

 

When trying to populate the word template, I created a blank page with literally just the placeholders on it e.g. <<name>> which is the same as my dynamic data from Forms and Excel.

 

Everytime, I get the same error code - "Failed to retrieve dynamic inputs. Error details: 'e.toLowerCase is not a function'". I've googled every solution and chatted it through with ChatGPT. Connections are working fine, I can find my template, I've created a brand new template with only placeholders, even tried curly brackets. Can't get this final step to work.

 

Any suggestions would be greatly appreciated.

    Hi @JTBright 

     

    I need to see the flow and mapping. I could do a screenshare and help. Please check your email. 

     

    Thanks

    The issue is I get a notification from MS Forms, but it contains none of the details.  Just the ID Number.

    I've share the errors above, but here it is again.  I don't get any details.

    The data being mapped to Sharepoint is only the ID Number...I want more fields from the form sent to Sharepoint list.

    Hope that helps,

    Could you please explain what the issue is? What error you are getting? What data you mapping to SharePoint?

    I'm having those problems in the Create Item step.  The previous two steps worked fine.  I need to add the fields from the response form to the Sharepoint list this creates.

    I agree, here is my flow:

    Hi @JTBright 

     

    That Get Response Details step should be outside the loop.

    Here we are.  I used the template and it works as I said before.  But there are no fields just the id number...I'm trying to add in the fields from the Sharepoint List seen here as "Request Form Output"

    Hi @JTBright 

     

    Could you post a screenshot of your flow? Also where exactly you needed the help?

     

    Thanks
