@arikfr Do you have any idea of what can be done here in order to resolve this issue?

[arikfr]

@batzsalmassi This happens because we're trying to generate a hash for a query that has no data source assigned to it (so the data source id is null).

I will make a fix for this, but you can work around it by either deleting these queries or assigning some data source to them.

Thank you so much for the reply!!
I'll try to find the empty queries and delete them, I'm waiting for the SAML Login issue to be fixed on V25.1 and after that I'll try to perform the upgrade again.

[arikfr]

@batzsalmassi what SAML issue are you referring to?

[batzsalmassi]

@arikfr I've raised this issue last week 7333
and @eradman has opened a PR that should fix the issue PR-7327

I encountered the same error mentioned in this issue while trying to upgrade to 25.1.0.

Today, after reading this comment, I tried deleting the queries with data_source_id is null along with their dependent data and then attempted the upgrade again, but the same error occurred.

I've been continuously upgrading my Redash instance since around v2.

It turned out that some old queries were still linked to an unused Python data source, which seemed to be the cause of the issue. Since those queries were no longer needed, I deleted them just like the ones with data_source_id is null.

After that, the upgrade to 25.1.0 completed successfully.

Thank you!

@take-take Thanks for the comment and share that it worked for you.
Did you logged into the Postgres DB itself to delete the queries or from the Redash portal?
