This simplifies the csv_from_savedobject logic by removing the async hook. This was added as premature optimization in the initial PR that added the Download CSV button to the dashboards.

There was a problem hiding this comment.
This line is what creates the complexity with getting Reporting to work with Task Manager. This CSV export handler uses the same methods other export types use for queuing, but that bind needs to be separated since this handler is responsible for "immediate" download of CSV without queuing.
By simplifying some TypeScript, this PR does enough to separate the bind to allow moving ahead with Task Manager work in Reporting.

## Summary This restores an endpoint that was added in 7.3 in [this PR](#34571), and was removed in 7.9 in [this PR](#71031). The changes are re-done on top of 7.17, but still has a mostly-compatible with the one that existed in 7.3-7.8. This serves 3rd parties that relied on the earlier experimental code. Supports: * Saved searches with filters * Saved searches with custom sorting * Saved searches with or without selected columns * Exports based on Index Patterns with or without a "time field" * Requests can have an [optional POST body](https://github.com/elastic/kibana/pull/148030/files#diff-0f565e26f3309c257fa919c5db227c3b7a78237015940c3d3677cbb1132a6701R27-R37) with extra time range filters and/or specify a custom time zone. LIMITATIONS: * This endpoint is currently not supported in 8.x at this time. * Saved Search objects created in older versions of Kibana may not work. * Searching across hundreds of shards in the query could cause Elasticsearch instability. * Some minor bugs in the output of the CSV may exist, such as fields not being formatted exactly as in the Discover table. * This code may be forward-ported to `main` in a way that uses a different API that is not compatible with this change. * Does not allow "raw state" to be merged with the Search object, as in the previous code. Otherwise, the API is compatible with the previous code. * This feature remains in "experimental" status, and is not ready to be documented at this time. ## Testing Since there is not a UI for this endpoint, there are a few options for testing: 1. Run the functional test: ```sh node scripts/functional_tests.js \ --config x-pack/test/reporting_api_integration/reporting_and_security.config.ts \ --grep 'CSV Generation from Saved Search ID' ``` 2. Create a saved search in Kibana, and use a script to send a request ```sh POST_URL="${HOST}/api/reporting/v1/generate/csv/saved-object/search:"$SAVED_SEARCH_ID ## Run transaction to generate a report, wait for execution completion, download the report, and send the # report as an email attachment # 1. Send a request to generate a report DOWNLOAD_PATH=$(curl --silent -XPOST "$POST_URL" -H "kbn-xsrf: kibana-reporting" -H "${AUTH_HEADER}" | jq -e -r ".payload.path | values") if [ -z "$DOWNLOAD_PATH" ]; then echo "Something went wrong! Could not send the request to generate a report!" 1>&2 # TEST curl --silent -XPOST "$POST_URL" -H "kbn-xsrf: kibana-reporting" -H "${AUTH_HEADER}" exit 1 fi # 2. Log the path used to download the report DOWNLOAD_PATH=${HOST}$DOWNLOAD_PATH echo Download path: $DOWNLOAD_PATH # 3. Wait for report execution to finish echo While the report is executing in the Kibana server, the reporting service will return a 503 status code response. STATUS='' while [[ -z $STATUS || $STATUS =~ .*503.* ]] do echo Waiting 5 seconds... sleep 5 STATUS=$(curl --silent --head "$DOWNLOAD_PATH" -H "${AUTH_HEADER}" | head -1) if [[ -z "$STATUS" || $STATUS =~ .*500.* ]]; then echo "Something went wrong! Could not request the report execution status!" 1>&2 curl "$DOWNLOAD_PATH" -H "${AUTH_HEADER}" 1>&2 exit 1 fi echo $STATUS done # 4. Download final report and show the contents in the console curl -v "$DOWNLOAD_PATH" -H "$AUTH_HEADER" ``` 3. Test that the above script from (2) works in 7.8, and continues to work after migrating to 7.17.

Summary
Follows #65213
Part of #64853
Closes #37471
Closes #62986
Some minor refactoring and hardening of the code that came up while working on Task Manager integration. These changes came from resolving TypeScript errors on over-complex and hard to test code.
This PR removes the async option of execution from
csv_from_savedobject. When that feature was added, it was opportunistic based on the way Kibana worked, and was possible due to the lack of TypeScript in Reporting and Kibana overall. It had the hope of becoming the next functionality of Export CSV from Discover, and benefit the code through more code reuse.The work on CSV exports and code re-use is happening in #67027
