Backup N8N workflows to Github

[mbowler]

Describe the issue/error/question

In the “Backup N8N workflows to GitHub” workflow, after the initial run I get an error on the ‘isDiffOrNew’ node. It seems to be an error on the 56th workflow to go through, though I’m not sure how to tell what is actually causing it or how to fix it.

What is the error message (if any)?

Within the node I get “Error: Unexpected end of JSON input [line 4]” with the following detail error.

SyntaxError: Unexpected end of JSON input

Just some additional information. The workflow that is failing has a few nodes with pinned data. Not sure if that matters.

I also noticed that the key “content” that comes in from the previous Merge node has no value when it fails on workflow 56.

Hey @mbowler,

What is in workflow 56?

[mbowler]

This is the workflow causing the issue. Not anything too crazy going on. (edit. looks like I have to split it into two parts due to character limit.)

Part 1
