Summarization Chain not summarizing

My summarization chains takes the following input with 12 items:

[
{...}, // 10 items
{...}, // 10 items
]

I then use this configuration:

My Individual Summary Prompt is to take the input variables and “Return a single line of valid JSON ONLY, no code-block fences.”

The Final Prompt to Combine is to take the {text} and take the “provided below as a JSON array, create one concise daily summary report for all”

However, I get this everytime:

How can I fix this? isn’t the purpose of this summarization chain to summarize into one output using an llm?
