[bug] cannot upload multiple artifacts under the same path

[nszczygl9]

What happened?

Version v3 allows to upload multiple files under the same path from different jobs which were executed using matrix.
After upgrading to v4.4.1 version I cannot upload many files under the same path, I get an error:

What did you expect to happen?

Is it possible to add this feature again?

How can we reproduce it?

try to upload few different files from different jobs which were executed using matrix: (test1.txt, test2.txt.test3.txt) under one path (for example test_results)

See this document: https://github.com/actions/upload-artifact/blob/main/docs/MIGRATION.md#multiple-uploads-to-the-same-named-artifact

Due to the architectural changes of artifact uploads for better speed, performance and reliability, we do not support multiple uploads to the same named artifact:

For your case:

different jobs which were executed using matrix

You can name the artifacts based on the matrix, and then download them all together.
