[nirinchev]

You haven't specified the version of the Realm SDK that you're using, but this appears to be a bug that was fixed in the latest version - can you try upgrading to confirm?

[nirinchev]

@ironage this appears to be similar to the encryption bug that you fixed, but continues to happen even with Core 14.6.1, which should contain the fix. Is there anything obvious from the stacktrace or something we can ask the reporter to try track it down?

[ironage]

Hi @clement-ilango the stack traces you provided show you are using a core version of v14.5.1, and the relevant fix is in v14.6.0. For the .Net SDK this is version 12.1.0 (2024-05-01) or later. Please try upgrading and let us know if this solves the issue. If not, please provide an updated stack trace, and send your Realm file with encryption key to [email protected].

[ironage]

@clement-ilango apologies, I missed this part of your latest message:

D:\a\realm-dotnet\realm-dotnet\wrappers\realm-core\src\realm/util/encrypted_file_mapping.hpp:184: [realm-core-14.6.1] Assertion failed: local_ndx < m_page_state.size() with (local_ndx, m_page_state.size(), size_t(addr), size_t(m_addr), m_page_shift) =  [85, 1, 1549425541120, 1549425508352, 16]

Which indicates that you are still seeing this on the updated version. Could you please still send the file to the email in my message above so that we can reproduce this and track down the issue?

[ironage]

@clement-ilango sorry, but I am unable to find your attachment when you respond by email to this thread. As far as I can tell, it is a limitation of Github's issue response system. Would you be able to send the file to [email protected] ?
