Google Slide Writer Variable Issues when using link as an input

I want to update variables in a specific Google Slide page and am having some issues.

Since I need to update a Slides file specific to the workflow, I want to pass in the link to that Slides file as an input.

Whenever i try and do this the node returns an error, but it works fine if i use the exact same link directly in the ‘link’ field (I did this as a test) - you can see it here.

Any help greatly appreciated!

Hey @samhbarton! If you’re reporting an issue with a flow or an error in a run, please include the run link and make sure it’s shareable so we can take a look.

  1. Find your run link on the history page. Format: https://www.gumloop.com/pipeline?run_id={{your_run_id}}&workbook_id={{workbook_id}}

  2. Make it shareable by clicking “Share” → ‘Anyone with the link can view’ in the top-left corner of the flow screen.

  3. Provide details about the issue—more context helps us troubleshoot faster.

Hey @samhbarton – Thanks for sharing this. I can see how this can be confusing. The way the ‘Link’ option works in the ‘Google Slides Writer’ is similar to how Google Sheet nodes function. The node requires you to select a file or manually add a link first so it can read its schema and output the available variables.

When you pass a link dynamically, the link or file isn’t “read” beforehand, so the node isn’t able to output the variables. For dynamic input, you need to define the link in the node manually first, and then you can pass the link dynamically.

The limitation here is that you can’t pass dynamic links where the variables in the slides are different, since for any new file you’d have to add it manually first. At the moment, this is a limitation of the node based on how it works.

OK thanks for the update @Wasay-Gumloop . So i guess at the moment there’s no way to accept a dynamic link where the variables are always the same across files?

So the file will be different each run, but the variables are identical each time

Actually its the opposite - You can pass in a dynamic file link as long as the variables stay the same on each file, if that changes then that would break the schema.

Oh! That’s exactly what I want to do. I’ll run another test and let you know if i encounter any issues

OK i gave it a go, still having issues.

So what I did was manually add a link and then specify the variables used and then remove the link and tried to dynamically pass the link in. And it wouldn’t let me put the link in.
