Do you want me to share the entire stack trace? Or what is the best way to get you the information you need?

Hi Buddy,

that looks like a bug.

Would you mind sharing your XQuery or a SSCE? I think this is definitely something we might want to have a look at :-)

I am all of a sudden getting the below error (and things were working just fine – weird). Works fine in 9.1.2 but not in 9.2.X. Any guidance would be greatly appreciated.

Note: I tried to send you an email with the full stack trace, but the moderator rejected it because the email was too long. I’ve cut down the size, but you now no longer have the full stack trace. If you need the full stack trace, please let me know how you’d like that shared with you.

Thanks, Buddy

It does exist. One of our employees ran in on 9.2.2, they were the first to discover the issue. Then I tried it on 9.2.0.

Hi Buddy,

The stack trace indicates that you are using BaseX 9.2.

Could you please check if the bug persists with the latest version 9.2.2?

Thanks in advance, Christian

Hi Buddy,

that looks like a bug.

Would you mind sharing your XQuery or a SSCE? I think this is definitely something we might want to have a look at :-)

I am all of a sudden getting the below error (and things were working just fine – weird). Works fine in 9.1.2 but not in 9.2.X. Any guidance would be greatly appreciated.

Note: I tried to send you an email with the full stack trace, but the moderator rejected it because the email was too long. I’ve cut down the size, but you now no longer have the full stack trace. If you need the full stack trace, please let me know how you’d like that shared with you.

Thanks, Buddy

Thanks. As Michael indicated, a self-contained query that allows us to reproduce the bug would be great.

It does exist. One of our employees ran in on 9.2.2, they were the first to discover the issue. Then I tried it on 9.2.0.

Hi Buddy,

The stack trace indicates that you are using BaseX 9.2.

Could you please check if the bug persists with the latest version 9.2.2?

Thanks in advance,

Christian

Hi Buddy,

that looks like a bug.

Would you mind sharing your XQuery or a SSCE?

I think this is definitely something we might want to have a look at :-)

Best from Konstanz

I am all of a sudden getting the below error (and things were working just fine – weird). Works fine in 9.1.2 but not in 9.2.X. Any guidance would be greatly appreciated.

Note: I tried to send you an email with the full stack trace, but the moderator rejected it because the email was too long. I’ve cut down the size, but you now no longer have the full stack trace. If you need the full stack trace, please let me know how you’d like that shared with you.

Thanks,
