The following formatting gives me this error - gets the following error error JSON capabilities.json : instance.dataViewMappings[0] is not exactly one from [subschema 0],[subschema 1],[subschema 2],[subschema 3],[subschema 4]
{ "dataRoles": [ { "displayName": "dbId", "name": "dbid", "kind": "Grouping" }, { "displayName": "URN", "name": "urn", "kind": "Measure" } ], "dataViewMappings": [ { "table": { "rows": { "for": { "in": "dbid" } } }, "single": { "role": "urn" } } ] }
Im sure it is a basic formatting issue but I can’t figure it out, would someone be able to advise ?
Thanks Tom
Hey,
The capabilities.json file require some parts even if they are empty:
{
"dataRoles": [
{
"displayName": "dbId",
"name": "dbid",
"kind": "Grouping"
},
{
"displayName": "URN",
"name": "urn",
"kind": "Measure"
}
],
"dataViewMappings": [
{
"table": {
"rows": {
"for": {
"in": "dbid"
}
}
},
"single": {
"role": "urn"
}
}
],
"objects" : [],
"privileges" : []
}
You should try it out.
If you wanna have fun you can watch the schema of a capabilities.json file 🤒 powerbi-visuals-api/schema.capabilities.json at main · microsoft/powerbi-visuals-api (github.com)
Maybe it won't work so please provide information about when and where does this error happen (when you start the custom, in the console etc...)
Thanks, have a good day
