create a calendar event on O365

Hi everybody,

I need some help for creating an flow that should create a calendar event.

My flow should look in my calendar for new events created and create a new calendar event in dependency to the new event.

First I check for the event subject to filter for some special contents and that is where my problems start.

In my first condition check I have used the following filter "@or(contains(triggerBody()?['Subject'], 'FIRST'),contains(triggerBody()?['Subject'], 'SECOND'),contains(triggerBody()?['Subject'], 'THIRD'))"

So it should check for the event subject if one of the three contents is inside that and go on with the flow or not...

But when creating an event I get a failure message:

" Unable to process template language expressions for action 'check_subject' at line '1' and column '2469': 'The template language function 'contains' expects its first argument 'collection' to be a dictionary (object), an array or a string. The provided value is of type 'Null'.'. "

From that message I would assume that the subject is empty, but it's not... at least not the event I've created

Maybe someone can also tell me how to dig a little deeper in some logs fom MS flow, because I cannot see what event that flow is just processing.

Thanks in advance.

Thomas

Hi @v-yamao-msft,

Well I used another event trigger "When an event is added, updated oder deleted" and changed it now.
Although it should have worked as I now haven't used any other filter for my first condition check, than only changing the trigger to "When a new event is created", as this would make more sense than my selection before...
but never the less, it should have worked with the other flow too...
So I think at first it is solved by changing my trigger to the other one, that fits more.

so thanks for that indirect hint 😉 as I saw the "When a new event is created" from your pictures.

Hi @Anonymous,

Do you want to create an event in a new calendar when an event contains specific subject is created in your calendar?

I have made the following flow, the condition is configured likes below:

@or(contains(triggerBody()?['Subject'], 'FIRST'),contains(triggerBody()?['Subject'], 'SECOND'),contains(triggerBody()?['Subject'], 'THIRD'))

It just works fine if the subject of the new event contains FIRST/SECOND/THIRD.

Please make sure the event does have a subject and try again with it.

Best regards,

Mabel Mao
