3274104 - RFC Adapter doesn't work after importing Adapter Metadata

After importing RFC Adapter Metadata into ESR, the RFC channels don't work. The channels don't start and they don't register on the Gateway. After collecting XPI Inspector Example 50 - channel trace - you see the following error in it:
