Writing to an NVRAM slot created with a password fails

[Melab]

I am using version 5.2 of these tools, from Ubuntu.

I first did:

tpm2_nvdefine -C o -s 4 -a "authwrite|authread" -p pass 0

Then I tried:

tpm2_nvwrite -C o -P pass -i file.txt 0

I got this error back:

WARNING:esys:src/tss2-esys/api/Esys_NV_Write.c:310:Esys_NV_Write_Finish() Received TPM Error 
ERROR:esys:src/tss2-esys/api/Esys_NV_Write.c:110:Esys_NV_Write() Esys Finish ErrorCode (0x000009a2) 
ERROR: Failed to write NV area at index 0x1000000
ERROR: Tss2_Sys_NV_Write(0x9A2) - tpm:session(1):authorization failure without DA implications
ERROR: Unable to run tpm2_nvwrite

I thought -P is supposed to be the option used to specify the password for an authwrite|authread protected NVRAM slot. Why isn't this working?

It should work with:
tpm2_nvwrite -P nvpass -i file.txt 0
with -C o pass is used to authenticate the owner hierarchy.
