Get file properties or used Get file content using path

I’m trying to use “Populate a Microsoft Word Template” to insert a signature image into an already existing Word document in SharePoint, but I keep getting a “NotFound” or “The provided workflow action input is not valid” error. I’m already using Get file properties and selecting the Id for the file or used Get file content using path , but it still doesn’t work. What is the correct way to update an existing Word document with an image in Power Automate?

@CU13101239-0,

Have you created the Word Template with content controls enabled?

@CU13101239-0 Please post a screenshot of the expanded Populate action so we can see what you're doing in there, along with any expressions being used.

@Tomac this is my problem now , Is the code writer's method correct? Note that if I remove the last comma, it shows "invalid"

@CU13101239-0 Try this for your dynamicFileSchema:

{ "-1990316577": "<your dynamic Outputs content>", "1066222620": { "$content-type": "image/jpg", "$content": "<your dynamic file content>" } }

Be sure to replace the parts in < > with your dynamic contents, but retain the quotes.

@Tomac

The situation remains the same, the output hasn't changed.

@CU13101239-0 Unfortunately, at this point we'll need to see much more of your flow to help resolve this issue. Screenshots of the whole flow, with full expanded actions that are relevant to this section including where you're getting the file content of the image.

We will also need the XML from your Word file and the filetype (regular docx or a Word template file?)

Partial screenshots will not be enough to figure out this issue.

@CU13101239-0 I just checked your duplicate thread on the issue and the additional information there is helpful. The action Get File Content Using Path returns the file content in base64, so you don't need to convert it to base64 in your flow. This may be causing your issue.
