• Var-itemUrl: to store the item url
• Var-siteUrl: can be a fixed value, or you can use the formula
  split(variables(‘Var-itemUrl’),’_layouts’)[0]
• Var-listID: to store the extracted listID
• Var-ListName: to store the final list name

Let’s go through some of the steps:

• We’re storing the itemurl in the var-itemurl
• Using that variable, we’re creating the var-listID variable, with following formula: split(split(variables(‘Var-itemUrl’),’%7B’)[3],’%7D’)[0]
• The last variable to fill, is the ListName. This is done in two steps:
  • First, query the site to get all lists
  • Then map the lists found to the listID we already have

And then you’ll notice you’re not getting the needed result, but just a blank result. The reason for this, is that the listID we retrieved from the itemUrl is in upper case, and the results we got from the ‘Get all lists and libraries’ is in lower case.

Solving the list-ID issue

The first time I went through the flow, assuming that I did everything correct of course, I was getting annoyed by lack of body content, without having any clean indication. It was when starting to compare and to play around that I noticed the discrepancy between the the result from the ItemUrl and the get all lists and libraries.

The solution is pretty easy (once you find the root cause); add a ‘toLower’

toLower(split(split(variables(‘Var-itemUrl’),’%7B’)[3],’%7D’)[0])

Publish and reuse

Now we’ve got this resolved, time to publish the flow. The negative thing here, is that users won’t be able to start the flow from the list actions, so we’re adding a direct link next to each item, by updating a custom column to show a direct link to start the flow, which we realize by adding following JSON:

{"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json", "elmType": "button","customRowAction": {"action": "executeFlow","actionParams": "{\"id\": \"{ID of your flow}"}"},"attributes": {"class": "ms-fontColor-themePrimary ms-fontColor-themeDarker--hover" },"style": {"border": "none","background-color": "transparent","cursor": "pointer"},"children": [{ "elmType": "span","attributes": {"iconName": "Flow"}, "style": {"padding-right": "6px"}},{"elmType": "span", "txtContent": "Request Approval"}]}
