flowContext does not work

General

Hi there
I have some troubles with flowContext in below flow. The local variable SollPosSchlafen is properly set as an integer? Is there a way to check the type of the variable??
On the other hand, the coser_set_pos does not work, allways get an error, that the value
"position" is " ". Any help on this ?? Thank you.

You specified data type as json in the HA node. You need to specify JSONata as json does not accept expressions.

Thank you.
You mean I only have to change to JSONata instead of JSON, anything else to change?

Yes you do not need {{ }} around the $flowContext("blahblah") expresssion

Tried nearly everything but could not made this working.
My last attempt was:

[{"id":"7371101dc880a49f","type":"inject","z":"b922c92e.707c28","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":811.5555057525635,"y":1557.7778272628784,"wires":[["c9a3e353ae50b1ad"]]},{"id":"dd7d326adb53e9ec","type":"debug","z":"b922c92e.707c28","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":1199.6825199127197,"y":1557.714319229126,"wires":[]},{"id":"c9a3e353ae50b1ad","type":"api-call-service","z":"b922c92e.707c28","name":"SollPosSchlafen","server":"a11aa034.815b8","version":5,"debugenabled":true,"domain":"cover","service":"set_cover_position","areaId":[],"deviceId":[],"entityId":["cover.rollo_schlafzimmer"],"data":"{ \"position\": \"{{$flowContext('SollPosSchlafen')}}\" }","dataType":"jsonata","mergeContext":"","mustacheAltTags":false,"outputProperties":[],"queue":"none","x":999.3333282470703,"y":1557.3333072662354,"wires":[["dd7d326adb53e9ec"]]},{"id":"a11aa034.815b8","type":"server","name":"Home Assistant","version":2,"addon":true,"rejectUnauthorizedCerts":true,"ha_boolean":"y|yes|true|on|home|open","connectionDelay":true,"cacheJson":true,"heartbeat":false,"heartbeatInterval":30}]

which gaves me following error:
21.2.2022, 19:56:27node: SollPosSchlafenmsg :

object

domain: "cover"

service: "set_cover_position"

data: object

position: "{{$flowContext('SollPosSchlafen')}}"

entity_id: "cover.rollo_schlafzimmer"

21.2.2022, 19:56:27node: SollPosSchlafenmsg : string[72]

"Call-service error. expected int for dictionary value @ data['position']"

Any further ideas or help?? Thank you - JJ

You did not follow my last post, I said you need to remove the {{ }} from around the flowContex().
e.g.

[{"id":"7371101dc880a49f","type":"inject","z":"bf9e1e33.030598","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":230,"y":1660,"wires":[["c9a3e353ae50b1ad"]]},{"id":"c9a3e353ae50b1ad","type":"api-call-service","z":"bf9e1e33.030598","name":"SollPosSchlafen","server":"a11aa034.815b8","version":5,"debugenabled":true,"domain":"cover","service":"set_cover_position","areaId":[],"deviceId":[],"entityId":["cover.rollo_schlafzimmer"],"data":"{ \"position\": $flowContext('SollPosSchlafen') }","dataType":"jsonata","mergeContext":"","mustacheAltTags":false,"outputProperties":[],"queue":"none","x":410,"y":1620,"wires":[["dd7d326adb53e9ec"]]},{"id":"dd7d326adb53e9ec","type":"debug","z":"bf9e1e33.030598","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","statusVal":"","statusType":"auto","x":618.1270141601562,"y":1659.9364919662476,"wires":[]}]

and the quotes are not require either.
