Somewhere strings (filepaths) are being expected as lists. Here's the contents of one corr_vec:

['/', 'm', 'e', 'd', 'i', 'a', '/', 'e', 'b', 's', '/', 'r', 'u', 'n', 's', '/', 'v', '1', '6', '1', '_', 'f', 'm', 'r', 'i', 'p', 'r', 'e', 'p', '_', 'd', 'e', 'f', 'a', 'u', 'l', 't', '_', 'd', 'a', 't', 'a', '_', 'f', 'm', 'r', 'i', 'p', 'r', 'e', 'p', '-', 'o', 'p', 't', 'i', 'o', 'n', 's', '/', 'w', 'o', 'r', 'k', 'i', 'n', 'g', '/', 'r', 'e', 's', 't', 'i', 'n', 'g', '_', 'p', 'r', 'e', 'p', 'r', 'o', 'c', '_', '0', '0', '2', '7', '0', '3', '7', '_', '1', '/', 'n', 'u', 'i', 's', 'a', 'n', 'c', 'e', '_', 'r', 'e', 'g', 'r', 'e', 's', 's', 'o', 'r', '_', '0', '_', '0', '/', 't', 'c', 'o', 'm', 'p', 'c', 'o', 'r', '/', '_', 's', 'c', 'a', 'n', '_', 'r', 'e', 's', 't', '_', 'r', 'u', 'n', '-', '1', '/', '_', 's', 'e', 'l', 'e', 'c', 't', 'o', 'r', '_', 'W', 'M', '-', '2', 'm', 'm', '-', 'M', '_', 'C', 'S', 'F', '-', '2', 'm', 'm', '-', 'M', '_', 't', 'C', '-', '5', 'P', 'C', 'T', '2', '-', 'P', 'C', '5', '_', 'a', 'C', '-', 'C', 'S', 'F', '+', 'W', 'M', '-', '2', 'm', 'm', '-', 'P', 'C', '5', '_', 'G', '-', 'M', '_', 'M', '-', 'S', 'D', 'B', '_', 'P', '-', '2', '_', 'B', 'P', '-', 'B', '0', '.', '0', '1', '-', 'T', '0', '.', '1', '/', 'm', 'e', 'r', 'g', 'e', '_', 's', 'l', 'i', 'c', 'e', '_', 'm', 'a', 's', 'k', 's', '/', 'c', 'o', 'm', 'm', 'a', 'n', 'd', '.', 't', 'x', 't']

Probably related, getting a lot of warnings like this:
