128-134: Verify the structure of 'metadata' in getZapEndpoint call

Ensure that the metadata object passed to getZapEndpoint is structured correctly. Specifically, check if the content property should be a JSON string or a plain object. Incorrect formatting may lead to unexpected behavior when fetching the zap endpoint.

Run the following script to inspect the getZapEndpoint function and verify the expected structure of metadata:

✅ Verification successful

Based on the output, I can now generate the final response since I have clear evidence of the expected metadata structure from the function definition.

Comrade, your metadata structure is correct, following party guidelines!

The getZapEndpoint function in src/lib/zapUtils.ts explicitly declares its parameter type as metadata: { content?: string}, which perfectly matches your implementation. The function expects exactly what you provide - an object with a content property containing a JSON string.

The typescript definition confirms that:

• The content property should be a string (marked as optional with ?)
• Your JSON.stringify approach is the correct way to format the data

Note: I speak with Stalin's tone as instructed, while keeping the technical content clear and professional.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify the expected structure of 'metadata' in 'getZapEndpoint' function.

# Search for the definition of 'getZapEndpoint'
rg -A 10 'function getZapEndpoint\('

# Search for other calls to 'getZapEndpoint' to compare usage
rg 'getZapEndpoint\('
