The documentation for that property from the C API [1] says it is of type GByteArray*, and the GJS source code seems to suggest that such values are explicitly not yet supported in GJS [2]. > Has someone a suggestion for a better solution? > If you just wanted the data you could use the 'certificate-pem' property [3]. As the documentation states, "This property and the “certificate” property represent the same data, just in different forms." However, it seems like you can't construct a Gcr.Certificate object from the PEM-encoded data. I don't have a good solution for this.
