e2e test failure during circuit compilation

[onsen-egg]

Hi, I've been trying to get the e2e test to run, am currently trying to work through the following error (at the end):

(base) [onsen-egg]$ ./e2e_test_recursive_proof_circom_verification.sh

Have not yet been able to solve this, any suggestions would be very appreciated :)

Turns out this was an issue with circom; I was on the latest version (v2.1.4), switching to v2.1.0 got rid of this problem. v2.1.3 was giving me the same error as well; seems that some kind of breaking change got introduced along the way.

I am using circom v2.1.5 and I take the same error, how can I change my version to 2.1.0
