Error while using proposed values in a form

Hello Data Citizens,
I encountered a pretty strange error while using proposed values for relation types in a form.
I get some relation type ids from the core api and then use them as the proposed values for a relation type selection in a user form.
The problem is that I get the following error when I want to select a relation type from the selection in the form:

The requested Relation Type(s) was/were not found for id(s) = [7ff7c914-42c2-4319-88df-087a8d136c72].

Which is true because for this UUID there is no relation type. The correct UUID is:

7ff7c914-42c2-4319-88df-87a8d136c728
(notice the 0 behind the last hyphen and the missing 8 at the end)

The interesting thing is that the core api does provide the correct UUID (I checked via console) so this might be a front end issue?
Does somebody have experience with this?

Sincerely,
Stefan

Hi @stefan.busch,

The relation type UUIDs are combined with the relation direction, which can be indicated by the following symbols:

“S” represents the source, indicating that the resource is the head of the relation.
“T” represents the target, indicating that the resource is the tail of the relation.

For example, the relation “Asset uses Asset” can be represented as “00000000-0000-0000-0000-000000007030S” to indicate that the first asset is the source of the relation and the second asset is the target.

Before utilizing UUIDs as values for relation type selection in a user form, can you try to concatenate them with the appropriate relation direction?

Satish

Hello Satish,

I tried concatenating the UUID as a string with an “S” but when i then try to cast it back to an UUID I get an error in the script stating that the string is too long to be converted to an UUID.

What I then tried is to use the concatenated value without converting it back to an UUID and that does indeed work.

Thank you very much!

Sincerely,
Stefan
