Migration from RH8.7 fails during repository fetch

[ygaillard]

I want to migrate a rh 8.7 (Ootpa) to rocky. However it fails on line 446 saying there is a bad subscript.

` Found the following repositories which map from Red Hat Enterprise Linux 8.7 (Ootpa) to Rocky Linux 8:

Getting system package names for Red Hat Enterprise Linux 8.7 (Ootpa)./migrate2rocky.sh: line 446: repoinfo_results_cache: bad array subscript
Error: Unknown repo: ''

Failed to fetch info for repository .

An error occurred while we were attempting to convert your system to Rocky Linux. Your system may be unstable. Script will now exit to prevent possible damage. `

I have only repository epel8 enabled. But it seems that it find no repository at all.

Can you please copy the entire migrate2rocky.log file from the failed attempt?
