We have such product structure

When I try to import product under size level in some cases I got alert and object are not created:

As You can see object exist but we got info:
[INFO] No object found for "Product:path:/Product catalog/1100 - Snake/TORE/11003 - Tech/Ø5x8cm; Socket: E27; Power: 4 W; Luminous flux: 320 lm"
and then strange array:

[INFO] Value for key field "path": Product:path:/Product catalog/1100 - Snake/TORE/11003 - Tech/Ø5x8cm; Socket: E27; Power: 4 W; Luminous flux: 320 lm -> {
    " E27": "",
    " Power: 4 W": "",
    " Luminous flux: 320 lm": ""
}

and then
[ALERT] Unable to process item: TypeError: strpos(): Argument #1 ($haystack) must be of type string, array given in

@BlackbitDevs ?

[betterapp]

I tried to replace " ; " for " + "

And now I see sometyhing like:
[INFO] Value for field path: Product:path:/Product catalog/1100 - Snake/TORE/11003 - Tech/Ø5x8cm+ Socket: E27+ Power: 4 W+ Luminous flux: 320 lm
[DEBUG] Trying to find target object(s) of class \Pimcore\Model\DataObject\Product with condition ((path = ? AND key = ?)) and variables [
"/Product catalog/1100 - Snake/TORE/11003 - Tech/",
"Ø5x8cm+ Socket"
]

why key use only "Ø5x8cm+ Socket" part of the whole string ?

[betterapp]

When I remove ' : ' it is working.

Looks like colon and semicolon can not be used in path name
is it DD issue or it working like this ?

Sorry for late response. You are right, the additional colons in Ø5x8cm+ Socket: E27+ Power: 4 W+ Luminous flux: 320 lm are the problem. For this reason, you can encapsulate the filter value with " (like in CSV): Please try to return
Product:path:"/Product catalog/1100 - Snake/TORE/11003 - Tech/Ø5x8cm; Socket: E27; Power: 4 W; Luminous flux: 320 lm"
in your callback function for Path.
