Hi,

I am using the Generate Word/PDF via Plumsail workflow (see below) and it has been working, however, I am getting the following error message which I cannot seem to resolve. Forum messages seem to indicate an issue with an expired token/licence?

I have checked the JSON data and it looks ok? Any assistance would be greatly appreciated.

"The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters."

Flow:

Error Message:

"headers": {

}

Many thanks,

Hi @SteveTaylor,

Might be a little late to respond, but if you haven't yet managed to solve the problem, please try my solution.

Using the "Create DOCX document from template" action implies using a certain file that will act as a template to generate your document from. The template must be applied to the "Template file" field. In your case, you inserted the form's ID instead of a file into this field, which ultimately caused the error.

There are two ways to fix this:

Create a DOCX document template and configure your flow according to this article. You may also find the following article useful: Word DOCX templates — Plumsail Documents
Create a Plumsail Documents process and bind your form to it.

Hope this helps! 🙂
