Netlify env branch/context needs to be case sensitive about cli

[zbobbert]

Here's my workaround using the Netlify API:

SET_ENV_DATA=$(jq -n \
  --arg account_id "$NETLIFY_ACCOUNT_ID" \
  --arg site_id "$NETLIFY_SITE_ID" \
  --arg context_parameter "$BRANCH_NAME" \
  --arg key "test_env_var" \
  --arg value "test_value" \
  '{ $account_id, $key, $site_id, body: { context: "branch", $context_parameter, $value } }')
UPDATED_ENV_DATA=$(netlify api setEnvVarValue --data "${SET_ENV_DATA}")```
