Error in 'get_annual_market_expectations'

[felipebrdesa]

Hello!

I'm trying to get market expectations with the rbcb package, but i came across with this message: "Error in .get_series(url) : BCB API Request error cannot open the connection".

Can you help me?

[raphaelrrcoelho]

Same problem here.

@raphaelrrcoelho @felipebrdesa please check out the last commit. Let me know if this doesn´t get solved.

Unfortunately, the issue remains. I'm trying this code: rbcb::get_annual_market_expectations(("Taxa de câmbio"), start_date = '2021-01-01').

[wilsonfreitas]

Please, try

get_annual_market_expectations("Câmbio",
                               start_date = '2021-01-01')

Taxa de câmbio no longer exists, they have changed.

[felipebrdesa]

Still doesn't work... i believe that it's a firewall block.

[wilsonfreitas]

Bad!

Try it

https://olinda.bcb.gov.br/olinda/servico/Expectativas/versao/v1/aplicacao#!/recursos/ExpectativasMercadoAnuais

You can export the results to a file and process the JSON with R.

I have the same error, could you fix it?

[wilsonfreitas]

No, I can't, there is nothing to be fixed. You should check your connection.

The last commit is working fine here.

It works again with the last commit. Thanks.

I changed the network connection and I'm still getting the same error Error in .get_series(url) : BCB API Request error cannot open the connection to 'https://olinda.bcb.gov.br/olinda/servico/Expectativas/versao/v1/odata/ExpectativasMercadoAnuais?%24filter=%28Indicador%20eq%20%27C%C3%A2mbio%27%29%20and%20Data%20ge%20%272021-01-01%27&%24format=application%2Fjson&%24orderby=Data%20desc&%24select=Indicador%2CIndicadorDetalhe%2CData%2CDataReferencia%2CMedia%2CMediana%2CDesvioPadrao%2CCoeficienteVariacao%2CMinimo%2CMaximo%2CnumeroRespondentes%2CbaseCalculo'

And when I try to connect to this link above, the error code below appears:

/{ "codigo" : 400, "mensagem" : "The property 'CoeficienteVariacao', used in a query expression, is not defined in type 'ExpectativaMercadoAnual'." }/

OBS: I used the same command as you above

@rmmaf have you updated with the last commit? If you updated correctly with the last commit this error should not be appearing.
