Intermittent failures trying to get URL asset URL

[beppler]

Most of the time the action works, but sometimes we receive the following error during the workflow execution:

jq: error (at <stdin>:1): Cannot index string with string "tag_name"

It appears to happen on this line of the script:

  asset_url=$(
      curl -s https://api.github.com/repos/peak/s5cmd/releases |
          jq --arg tag "${tag}" --arg asset_name "${asset_name}" '.[]| select(.tag_name==$tag) | .assets[].browser_download_url | select(. | test(".+" + $asset_name + "$"))' | xargs
  )

It appears that the releases endpoint responded with a invalid json, but I can't confirm it.
