Chainlink multi-variable responses - results not getting appended - ethereum

Question

I'm trying to implement a multi-variable job on my local node, however I'm finding that only 1 of the 3 results are being added to the chainlink_result_collection array in the resultcollect task. My definition is very similar to the example one linked, the main difference being the use of an external adapter
Running the above example smart contract and spec on my node works, and gives the following output. Take note of the chainlink_result_collection array being appended to after each run. Have linked the output file to stay under the 30k size limit for SO posts
However when I try to run my multi-variable job, I get the following output. Take note of the chainlink_result_collection after each resultcollect task. You can see each time it's being set to the latest return value, instead of being appended to like the previous job output. So the length of the chainlink_result_collection array at the end is 1 instead of 3 elements

Answer 1

the issue is that the 'chainlink_result_collection' array is not passed through from the resultsCollect to the EA (external adapter) call, whereas it is from resultsCollect to a normal HTTP Get task. I verified this by creating a job that contains 3 requests (EA, HTTPGET, EA), and observed that at the resultsCollect for the HTTPGet, the array correctly had 2 values, however on the final request (EA), the array didn't get passed through to the EA task, and the end result was just the 1 return value from the final EA
There's an open issue on this at the Chainlink GitHub
