Hi, I have the same issue and only a!EXAMPLE_DOCUMENT_IMAGE() works without an error, but of cause delivers the placeholder images.

----

a!documentImage(
document: a!EXAMPLE_DOCUMENT_IMAGE()
)

Causes the error:

Error Evaluating UI Expression

Expression evaluation error at function a!gridField_23r3 [line 51]: A grid component [label="null"] has an invalid value for "columns". A grid column [label="Image"] has encountered an error. Expression evaluation error at function a!documentImage [line 53]: Could not cast from DocumentImage to Document. Details: CastInvalidCould not cast from DocumentImage to Document. Details: CastInvalid

----

if(
a!isNullOrEmpty(
fv!row[recordType!W"" Vehicle.fields.image]
),
a!EXAMPLE_DOCUMENT_IMAGE(),
fv!row[recordType!W"" Vehicle.fields.image])

as stated in the course, causes the error:

Error Evaluating UI Expression

Expression evaluation error at function a!gridField_23r3 [line 51]: A grid component [label="null"] has an invalid value for "columns". A grid column [label="Image"] has encountered an error. Expression evaluation error at function a!imageField [line 52]: User Does Not Have Rights to Perform this Operation

----

How can this issue be resolved and images be shown?

As I still couldn't get it to work I have not saved te changes and have left the expression as follows:

if(
a!isNullOrEmpty(
fv!row['recordType!W0SA Vehicle.fields.image']
),
a!EXAMPLE_DOCUMENT_IMAGE(),
fv!row['recordType!W0SA Vehicle.fields.image']
)

I am still recieving the following error message:

Expression evaluation error at function a!gridField_23r3 [line 51]: A grid component [label="null"] has an invalid value for "columns". A grid column [label="Image"] has encountered an error. Expression evaluation error at function a!imageField [line 52]: User Does Not Have Rights to Perform this Operation

I have read up a bit on images in Documentation. Am not sure what I need to do. I google translated the conversation above but am not sure how to carry out the advise given.

Hi calebs2672

I suspect you have an older workspace that contains an image identifier in your vehicle record that you do not have access to. While this issue has been resolved for newer workspaces, you can resolve the issue by updating your expression as seen below. Keep in mind that this will cause all vehicles to have the placeholder image - but will resolve your issue.

Hope this helps!

I uploaded the image you plaeced at the bottom and aded it in as a!EXAMPLE_DOCUMNET_IMAGE(cons!W0SA_PASTEDIMAGEPNG) but then I got the following error: The rule 'EXAMPLE_DOCUMENT_IMAGE' [line 5] has 0 parameter(s), but instead passed 1 parameter(s).

Según mi sugerencia, puede mantener una "imagen sin imagen disponible" y usarla de forma predeterminada. Cuando no tenga ningún valor, aparecerá esa imagen.

Like that.

De acuerdo ya lo llegue a hacer y no me sale el error. Pero ojo que ahora, en todos los formularios
y vistas que se hagan para el usuario no va a salir la imagen de default para aquellos registros en los
cuales el campo imagen tenga el valor null.

Por favor, pásame como te quedo el código.

Debe pasar la imagen (valor generado por Appian del documento) en lugar de pasar a! EXAMPLE_DOCUMENT_IMAGE()

RE: Step-by-Step #5 - Format the Image column

marioeduardok6808 — Fri, 20 Sep 2024 07:13:29 GMT

No, sigue sin funcionar (pero si el error es el del registro, tampoco pude borrar el mismo).
Creo que voy a avanzar en la parte teórica en lugar de seguir perdiendo el tiempo con los ejercicios paso a paso.

Can you please tell me what are you passing in a!EXAMPLE_DOCUMNET_IMAGE()?

Tengo el mismo problema en el STEP 5 con el campo IMAGE y estoy sospechando que el problema sea debido a
que el último registro de los registros copiados el 33 tenga un valor que no es nulo y es numérico.
Pero no me deja borrarlo para poder verificarlo.

I am using a!documentImage. This is what I currently have per the lesson's instructions:

Can you please use a!documentImage instead of a!imagefield ?

Am having the same issue. Am recieving the following text:

Expression evaluation error at function a!gridField_23r3 [line 51]: A grid component [label="null"] has an invalid value for "columns". A grid column [label="Image"] has encountered an error. Expression evaluation error at function a!imageField [line 52]: User Does Not Have Rights to Perform this Operation

Not sure what folder I am supposed to be checking as the vehicle images don't come from the Acme Automobile application.

I have the same issue, we don't have permissions to the Vehicle Images. Did you find any solutions yet?

Hi princessm4196 ,

The image which is referenced in the grid filed is uploaded to a folder, and the user trying to view the record does not have access to view the contents of that folder.

You need to change the permissions of the folder to Viewer for a basic user to be able to view the iamge. you can refer to Folder and Document Management

Hi princessm4196 ,

Once check the folder security where the Image target is given. May be there you don't have enough Privileges for that folder. Please check.
