Error running update query

One of my pages have an SQL query binding on a custom property named dsBollaData - a SELECT statement with a WHERE clause based on another custom property

The other components draw there values from the custom property dsBollaData by means of a lookup.
If I login/logout when that page is displayed I get the following error message:

as if the dsBollaData custom property had an UPDATE statement too, which is not the case.

Ignition version: 7.9.8 (b2018060714)
Java version: 1.8.0_172

Any suggestion?

Thanks in advance, regards

Update to 7.9.9; this is a bug that was present in 7.9.7 and 7.9.8.

Many thanks, I will do it as soon as I can.
