Ref #15211

[hcderaad]

I had similar issues, applying the following PR manually fixed it for me: https://github.com/nextcloud/server/pull/15385/files/471827cb3143fc55f4e280128dad063c9e876a59 also valid for #15393

[kesselb]

Thank you @hcderaad

The problem isn't fixed for me. I applied pr #15385 but shared folders from other instances are still inaccessible

and will throw mentioned SQL error.

Update: The instance owning the federated share must be patched...

Please see my comment #15385 (comment): I think another instance should never be able to cause such a problem and occ files:scan --all should not fail. I.e. if another instance is sending invalid data NC should detect that and maybe suspend federated share but don't fail like shown above.
