What is the correct format for the contributors list in the manifest, I see some complains:

Could not parse `manifest.contributors` from nextflow.config. Expected a list of maps, for example: []. Normalised string passed to JSON parser was:
[{...},{...}]
JSON decoding error: Expecting ',' delimiter: line 1 column 3144 (char 3143)
No authors found in pipeline manifest. Proceeding without adding authors to the RO-Crate.

Weird thing I notice, the last entry, from the last contributo given back by tools is

"contribution":["contributor"}]

, while all other similar entries are

"contribution":["contributor"]}

. Notice how the

}

is weirdly placed. Any idea?
