Hi all,

I have created an entity form and want that users are able create Dynamics 365 records with it. However I am getting the following error, when I fill out the form and click submit: "The given key was not present in the dictionary. (source: mscorlib)". There are no error details.

I created entity permissions for the main entity and all the other related entities, which has a subgrid in this entity form. I also assigned the right web roles to these entity permissions but the error still consists. I also have other entity forms and they work perfectly.

Any idea, how to resolve this problem?

Thanks in advance,

Selim

Hi @selimdag
besides the usual things like cache clearing and restarting the portal: could it be, tht there is a plugin rgistered on the entity? I sometime create pluginsteps accidentially by hitting enter on setting up pluginsteps which save the steps (for example, when i choose the message) (bad interfacing in the usual pluginregistrationtools...) before the setup is finished...
This leeds sometimes to this kind of problems.
Just a hint, no solution.

Have fun,
Christian

do you have any plugins/workflows associated to that entity? can you deactivate it to test?
maybe the error isn't really the portal, but another process linked to the entity

@chleverenz, @OliverRodrigues

Thank you for your answers.
The problem was a workflow in Dynamics 365. Deactivating the Workflow made the error disappear. It is weird because the workflow itself doesn't cause any problem in Dynamics 365. But when I create a Record by the Portal, it throws me this error.

Hi together,
good to hear you found the problem.
This is a very common problem in my projects, because plugins/workflows rely on data which might not be present when the request was created by the protal.
We usually add a listbox to each entity we use in the portal and set the value to "sent by portal" (via entity form metadata) when the request is submitted.
Then other processes have a fair chance to ignore the event when something happens 🙂

Have fun,
Christian
