Error creating DOCX from template in MS Flow

Before anyone points out this error is in MS Flow (Power Automate) I am aware, but raising here as nobody on the MS forums could help.

I am using the Create DOCX from Template function as the final stage of an annual appraisal process. This works fine in other stages, but when trying to add this as a later step in a flow I am getting the following error:

Flow save failed with code 'OpenApiOperationParameterValidationFailed' and message 'Input parameter 'request' validation failed in workflow operation 'Create_DOCX_document_from_template': The API operation 'FlowV1DocumentsJobsApplyDocxTemplatePost' requires the property 'request/data' to be of type 'Object' but is of type 'Array'.'.

Anyone have any idea what this means and how to address it? I cam provide screenshots if necessary.

Hello @mouseharden,

Please try the action again and if it fails share with me the flow screenshots in Edit mode, the source DOCX template and the JSON. You can also send it to support@plumsail.com
