Sharepoint File to Planner Task with attachment

[paul1981]

I have created a flow that makes a new Task in Planner everytime I drop a file in a specific folder (and adds a due date to the Task). I would like to then add the file as an attachment (or link) to the Task in Planner. I have followed some other posts and created a sharing link for the file, but when the flow runs it always fails at the point when I try to add the link 

Any suggestions what I am doing wrong 

Thanks in advance

Mmmmm... did you play with 'References type' possible values?

Hope this helps

Hi @efialttes 

Thanks for the response - I have tried changing 'References type' to .pdf (which is what i'm trying to attach) but it gives the same error. I am presuming it is to do with the sharing link I am creating, but when I click on that in the output code ('resourceLink') it takes me to the file I want to link to. Feels like i'm missing something obvious 

Below is my complete flow - Folder location is a Teams folder but with a sharepoint behind it

Just reading the Planner graph API doc, according to the following link...

https://docs.microsoft.com/en-us/graph/api/resources/plannerexternalreferences?view=graph-rest-1.0

"Properties

Properties of an Open Type can be defined by the client. In this case, the client must provide valid URLs based on the HTTP/HTTPS protocols as properties and their values must be the externalReference objects. Based on OData, property names in Open Types cannot contain the following characters: ., :, %, @, # so they need to be encoded. Example is shown below. To remove a reference, set the value of the property to null."

I would try to convert dot characters on your URL into %2E
