can not add record of TXT for same RRset

[oyJouokong]

Short description

i have a zone like 'example.rpz'
and there is a type of A record as
storage.example.rpz IN A 192.168.0.0.1

and then i want to add a type of TXT record like:
storage.example.rpz IN TXT "region=cn"

and the api response get an error as:
RRset storage.example.rpz. IN TXT: Conflicts with pre-existing RRset

Environment

powerdns 4.4.1

Expected behaviour

different type of record can add success

Actual behaviour

can not add record of TXT for same rr

is there any limit here?

You are using an unsupported version. Please upgrade. See https://repo.powerdns.com

There are very few restrictions, but an important one is that you cannot have a CNAME record together with another type of record for a specific name.

Please show the exact requests you are doing and the full replies, plus all existing records before yo are trying to add a record.

That is, there can't be rr of cname and rr of txt type the same?
or can i fix this problem by upgrade the pdns version ?

The DNS protocol doesn't allow it. Upgrading PowerDNS won't change that.

But if you're having a different issue, upgrading PowerDNS might fix it or make it easier to debug.

192.168.0.0.1 is an invalid IP address, for what it's worth. It's too long.

192.168.0.0.1 is an invalid IP address, for what it's worth. It's too long.
Sorry, I wrote that IP wrong. Actually, it has nothing to do with this IP. Type A records have been added successfully, such as:
storage.example.rpz IN A 192.168.0.1

I am now, add the above records, and then add the following TXT records, it is wrong
storage.example.rpz IN TXT "region=cn"

so my demand that i can also add this TXT for same rr record

[Habbie]

please show SELECT * FROM records WHERE domain_id=19454

[oyJouokong]

may be i found the problems
Could it be that my same rrset is a CNAME type, causing it to fail? I tried to add successfully if type is type A, but originally when I used recursor to read the specified db.rpz file, record was also written like this

db.rpz：

test.example.rpz IN A 10.0.0.1
storage.gz.example.rpz IN CNAME test.example.rpz
storage.example.rpz IN CNAME storage.gz.example.rpz
storage.example.rpz IN TXT "region=cn"

Then use the file recursor.lua, which reads:
rpzFile("./db.rpz")

This is the correct resolution of these CNAME and TXT records, and now I save these records to the authoritative, it will not work.

[Habbie]

that is not what I asked for. However, it does show the presence of a CNAME, which does not allow any other records to co-exist with it.

[omoerbeek]

According to the DNS RFCs, you cannot have a CNAME record together with other types for a name. That is fundamental to DNS. I told that already in the first reply.

Ok, I see, Thank you very much for you patience. And then I'll see how I can fix it.
