unable to decrypt the encrypted messages using sjcl 256 gcm- tag mismatch error

[AmrithGanesh]

Hello,

We are using the SJCL code to encrypt our payload using the sjcl-256-gcm algorithm. This issue occurs only sometimes and the next time we try, the encryption is good.
Error we receive while decryption is

sjcl.mode.gcm={name:"gcm",encrypt:function(a,b,c,d,e){var f=b.slice(0);b=sjcl.bitArray;d=d||[];a=sjcl.mode.gcm.C(!0,a,f,d,c,e||128);return b.concat(a.data,a.tag)},decrypt:function(a,b,c,d,e){var f=b.slice(0),g=sjcl.bitArray,h=g.bitLength(f);e=e||128;d=d||[];e<=h?(b=g.bitSlice(f,h-e),f=g.bitSlice(f,0,h-e)):(b=f,f=[]);a=sjcl.mode.gcm.C(!1,a,f,d,c,e);if(!g.equal(a.tag,b))throw new sjcl.exception.corrupt("gcm: tag doesn't match");return a.data},ka:function(a,b){var c,d,e,f,g,h=sjcl.bitArray.i;e=[0,0,

             ^

corrupt {
toString: [Function (anonymous)],
message: "gcm: tag doesn't match"
}

is there any patch required for this?
below is the data
