Hello all,

 

I am encountering an issue when using MergePDF Power Automate step. So far, I have followed https://blog.developer.adobe.com/merging-documents-using-microsoft-power-automate-69a68e46081b. 

 

 

 

 Below is The results of testing my flow with the error "

CORRUPT_DOCUMENT: The input file appears to be corrupted and cannot be processed

"

 Here is also a snippet of the parameter input. I see that the files are sent as Base64 encoded. I decoded these and am able to view the PDFs which tell me they are valid documents. 

 

parameters":{"Files Array/outputFileName":"merged.pdf","Files Array/files":["[{\"$content-type\":\"application/octet-stream\",\"$content\":\"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....

 

    Correct answer Raymond Camden

    It looks like you passed an array in Files Content -1, but it expects one file.

    Enter this edit mode and remove the square brackets, leaving only the variable.

    Thank you Raymond. When building this I was using the "New Designer" and missed the "Switch to input entire array" step
