Copying a large study fails

[elisabettai]

Following up on this message I'm creating a new issue.

On AWS staging, if I try to copy the project "Study with big files and annoying services" (shared with all devs, uuid a94dc17c-3efc-11ed-96ce-02420a0b1f13) I get an "Unexpected client error". Is this expected @sanderegg, @odeimaiz?

Backend claims that the process is finished almost right away, but, apparently it's not

Maybe two useful pieces of information:

1. In the DB, I see that copies exist (uuid 7eeb2214-5511-11ed-8da5-02420a0b0092 and 30bddde6-550e-11ed-8da5-02420a0b0092)
2. One of the node (cb581308-75f6-497b-9509-4ae923b46e3a in the original study a94dc17c-3efc-11ed-96ce-02420a0b1f13) has files in output_1 and output_2 with the same name. Is this maybe related to if 2 output files have the same name the upload of outputs fails #752

Regarding point 2 on my comment above: I deleted the output files that have the same name, to exclude that the copy error was somewhat related to the known bug.

Still I can't copy it (copying other studies work). Maybe worth having a quick look before the release to prod next week @sanderegg?
