Appflow build for Android fails: Illegal character in opaque part at index 2: C:\Keystore\---.jks

Hello,

I need help with Package Build 7180429, trying to build Ionic Vue for Android. I only just purchased Appflow, but unfortunately it is not yet working out of the box for me. I am getting the following error. Any ideas?

[13:31:54]: Shell command exited with exit status 1 instead of 0.
