Merging fails when multiple licenses are in codemeta.json #450
Description
When there are more than one license listed in codemeta.json, the merging process fails.
After harvesting metadata from both CITATION.cff and codemeta.json, hermes encounters an error during the merge step, and does not generate hermes.json.
Example
codemeta.json:
"license": [
"https://spdx.org/licenses/Apache-2.0",
"https://spdx.org/licenses/CC-BY-4.0",
"https://spdx.org/licenses/CC0-1.0"
]
CITATION.cff:
license: Apache-2.0
The licenses are correctly harvested, but the merging process fails when multiple licenses are presented in the harvest results, and the hermes.json file is not created.
