Create Teams Meeting with recurrence - "UnableToDeserializePostBody"

[AsaurdiffADTill]

I know there are other posts about this function. I also know that NO ONE can seem to answer most of them. It would be great to get a Dev or true pro to answer this question. 

I am creating a solution that "imitates" users actions in Teams/Outlook meeting creations. My Org needs to utlize this solution to automatically add details to the requests. I have been able to post meetings and Teams meetings to the rooms and calendars. Its almost identical, feature to feature, to what you can do with Outlook/Teams for meetings BUT it can't handle recurrence yet. I have seen some users able to create recurring meetings, but i can't reproduce their examples either. 

I have looked into the Graph API syntax of this function to try and reproduce options. I know that i may be able to create a custom connector, but that is NOT an option because of licensing. Generally these connectors are 1-1 for Graph, considering thats what they are using. 

EITHER WAY:

I am currently testing "daily" type recurrence. I have store a record variable, syntax shown below, and past it to the recurrence key the connector recomends using. It even insisted on specific key/values that i forced in. Every time i run it i get the "UnableToDeserializePostBody". Previously, this was seen as a syntax error (other posts i've done) but all i can see on network debugging is it refuses to send the recurrence.range.type over. I can't force it either. Any help would be appreciated. 

Recurrence record syntax: 

pattern:{type: "daily",
 interval: 2,
 daysOfWeek: [""],
 index: "first"
}
range:{
startDate: "1/19/2023 12:00 AM",
 endDate: "1/26/2023 12:00 AM"
//,(not sent) type:"endDate"
}//notice how the type isn't sending

Ill reply to my own question. Not sure if anyone will take this one on anyway haha. 

The deserialized is the lack of syntax the JSON has. I "believe" i solved this issue by setting the date formats in the Range object to "yyyy-mm-dd" this is how its needed to deserialize properly. 

As of now the function requests that you ALWAYS use "daysOfWeek" key/value but seems to ignore it. I have setup a "daily" type recurrence. With an endDate (it totally ignores ANY range type btw, only uses endDate so far) and fill in the "daysOfWeek" collection with M-F , no Saturday or Sunday, and it still books on those days. 

So any pointers on this would be helpful. I think at this point ill work on this and keep this thread updated with my findings. A blog on the function i guess. Since there is NO thourough documentation on it that i've seen. #ShameOnMSoft...

Hi @AsaurdiffADTill ,

Glad to see you have a solution to your problem.

You could mark your answer/solution as a 'Solution' to allow more people with the same problem to solve their own problem as quickly as possible.

Thank you so much!

I accepted this as a solution to the deserialization problem. You need it to be in the yyyy-mm-dd format. 

ALSO NOTE: This connector/function does NOT accept all data. It ignores Range-Type, numberOfOccurrences, FirstDayOfWeek and many more. Although required, it seems to ignore the "daysOfWeek" collection it requests. This is supposed to restrict the days the user is allowed to book in or the days they are booking in. (as per my interpretation of the documentation). But this is another problem to resolve.
